So I am in a very similar boat, but with some added sexuality and gender identity problems
I'm a white cis-male (tumblrspeak, ugh), and I like being a man, so I can't really relate whatsoever to gender-identity-problems whatsoever, but I think I can relate some on the sexuality part.
I've always been attracted to girls, both emotionally and sexually. My dad kicked me out when I was 17 (I'm 23 now), and that's when I met my best friend. He owns a driving school, and he is a driving school teacher, so when I was getting my liscence, I drove with him. A week before I started working on the liscence, I met him at the gym, and talked with him. He was a former friend of my mom, and he had heard about the situation that I got kicked out, so he took it upon himself to help me out with weightlifting (he's a former pro bodybuilder, and has won 2 nation's heavyweight classic titles where I'm from). I remember the first time I saw him, my first impression was basically; "holy fuck, he looks great, I wish I looked like that".
I've never had a rolemodel, and my dad has always been a condescending fucking asshole to me, so I've never, ever, had a father figure either. So when my now best friend stepped up and basically wanted to be my friend and help me out, he instantly took that place, if that makes sense. Not like, a dad, but father figure-y, and my rolemodel.
After over a year, almost two maybe, I started feeling sexually attracted to him, which was superconfusing/conflicting for me. Since then, I've tried checking out other men/guys, and watched some gay porn, but nothing/nobody else ever interested me whatsoever, except slightly big weightlifter-types. Strongman/bodybuilder-stuff, but even that didn't really sexually interest me, more like "wow, that looks great" and an appriciative thing, of masculinity, if that makes sense. My second best friend (who died late August 2015) was a competitive strongman in the country where I'm from, he got me interested in weightlifting before this. I always thought he looked pretty good too, but never anything sexual, back then. By the time I hit 20, I was interested in him, too.
Anyways, yeah, I started liking my best friend sexually, but I never wanted to fuck him or anything, just, I have no idea how to explain this. So when we first did MDMA (his wife was there with us, me and her are really good friends), I talked about my issues growing up, and told him about how hard it was for me to connect with other people, and that he was the first person I had felt really cared about me genuinely, and that I was able to return the feeling, and eventually, I had done that towards his son, and his wife too, and how great it felt. My best friend is very cuddley; he grew up with a shitty dad too, who never hugged him or anything. So he's the biggest teddybear towards his wife, and his son. During the MDMA round, we cuddled probably for 3-4 hours straight. Just hugging, handholding etc. His wife thought it was hillarious.
The next round we were gonna go for, both him and his wife wanted me to invite my ex "girlfriend". Me and her had never officially been a thing, but we were "dating" for 3 months, and had been really good friends for a few years (age 17-20) before we lost touch, and I recently met her again. We invited her for the roll, and we basically ended up fucking her while his wife watched etc, and again, lots of cuddling, between all of us.
He crushed on my ex gf for a bit after that, (she's also 23, my best friend is 48, his wife is 42, just for context), and this isn't really significant other than to give some context. She didn't really display that much interest back, eventhough she was the first to suggest that we all should hang out the next weekend. She went no signal for a bit, and my best friend got upset, and basically said something along the lines of "fuck that girl, if I had asked you to suck me off, you'd drop to your knees and do it right now:", which was a bit weird to me, considering his wife was sitting there in the room, too. That's when we discussed the sexuality part, and I admitted to both of them that I was somewhat sexually interested in him, but I had no idea why or why it happened, and I told them that this was a recent thing, and it wasn't like I wanted to fuck him or anything. I told them that, that I wouldn't even have fucked him if I had been paid 100K$ to do so, and if I wanted to do anything with him, it would basically be to blow him or some shit. I also admitted that I felt similiar towards my second best friend mentiond above, but never towards anybody else my entire life, and that I was still super interested in girls, which they believed, I mean, we had just had that nice weekend with my ex. His wife is okay with all of this btw, because I told them that I didn't want to be, and that I wanted anything above else to just be friends with them. Even after all of this, me and him, we still cuddle. Like, hold hands etc, just chill in bed for an hour or two where we just hold around eachother, and when we do this, I don't feel any sexual attraction, not even with me.
So I'm still confused on the sexuality part. I like girls, a lot, and so far, I've been sexually interested in two guys, and I slept with my second best friend before he died around half a year ago. I blew him, he blew me (he was 29). I thought it was okay, but not nearly as interesting as with girls, but I didn't dislike it. I prefered just cuddling with him way more (this friend was on MDMA, while I was sober/a joint or two).
Anyways, even after all of this, me and my best friend still cuddle, we talk/text several times a week, always hearts, shit like that, and hold hands every now and then, always super big bear hugs, and even before he knew that I was kinda into him, he had no issues walking around in boxers/naked (like, if we had been at the gym, went back home to shower etc), he'd just walk around naked to find new clothes etc, and he's never stopped this behavior, even after I've admitted that I kinda wanna blow him. Anyways, point is, when we cuddle, even when just in boxers/naked etc, I don't really think about him sexually. His wife is a bit of an exhibitionist, so she wanted me to watch while he fucked her, and I've done that twice. My best friend was super uncomfortable with that, so I wasn't really okay with it either, so both me and him had to tell his wife that we couldn't really keep doing it, so it's pretty clear that there's lots of boundrary-respect here.
The first time we full out naked cuddled was after the MDMA round with my ex, because he fell a bit in love with her, so the morning after, he was a bit upset, so his wife came and woke me up and told me to go talk to him, while she and my ex made breakfast.
When I went in, I just went and sat by the bed on the floor, so he asked me to come up in bed with him, and he wanted to cuddle, so we laid there for about two hours, cuddling, while he said he was feeling super guilty, because he had fallen in love with my ex, and he wasn't sure if he should tell his wife or not. I told him it was too early to say if he fell in love with her, or if it was just the MDMA spark, so I told him to just wait for a bit. 5-6 days later, it was gone, but he still likes her a lot. She's hung out with us a few times after that, too, and he's fucked her a few more times (him and his wife sharing her etc), so that passed by.
I keep telling myself it's just because I was on ecstasy that I had that strong moment of intimate... one-mindedness? with him... but I don't really know anymore.
If it's been over 2-3 weeks, then it's probably not the MDMA making you feel that way, it would blow over, I think. That's basically why I wrote this long rant of a post, to try and relate I guess. He fell in love with my ex on MDMA, but it went over pretty fast. I'm still a bit conflicted. I'm either straight, or bisexual, or somewhere inbetween.
Again, sorry for the long response.
