I'm normally a lurker, but we are so similar that I feel I have to share! I am 27/f and have the same thoughts/fantasies, and I do not think you are bi (however, you could be! Just not by what you have described). For me, I've always looked at boobs/butts more often than I look at men. Women are seen as sex objects by society, and basically women are 'sexy'. When I watch porn, the female turns me on just as much as the man and/or the act, and many times the woman turns me on more than the man. During sex irl, often times it is my own sounds that turn me on (as well as the pleasure! :) ). I'm not the best at explaining, but to put it short, this is normal. Many women are insecure about this, as they think this makes them lesbian/bi, etc. but doesn't!

When I imagine myself with a partner in the long term (marriage), I always think of a male. Not because this is the norm, but because I really do feel an intimate, emotional, loving relationship with men, that I do not feel with women. I have actually done sexual acts with women before, and honestly it kinda grossed me out :/ However watching women in porn, looking at women, and thinking about women sexually turns me on. What I've heard before is that society spends so much time sexualizing women that even women start to look at other women as sex objects, even if they are not sexually inclined towards women.

So, there are a few questions to ask yourself: Do you feel any long-lasting non-sexual emotions with women? For example, for me it's purely sexual: I enjoy watching women in porn. However when I imagine holding hands, kissing, massaging, loving, supporting, caressing a woman, it makes me cringe! There is a line there that is hard to explain (I'm not the best with words!). For me the only thought I have with women are sexual. With men, there are many more emotions, and even though I also think about men sexually, I often think about women more often! I even would look at gonewild posts, watch girls masterbate (lol), etc. It really is a "soceity" thing where women are sexy. This doesn't mean that I should marry a woman.

As for the "tingles" thing, I TOTALLY know what you mean!! I love getting my hair done because whenever any stranger touches/brushes up against me I get this wave of tingles haha! For me I don't think it's a sexuality thing, because really I have no feelings for the person doing it, it's just the sensation of a stranger touching me and it's such a great feel! It feels just like how "butterflies" feel when you first get to know someone. This is pretty darn normal! It started happening to me more when I started to have anxiety problems, so I think it's just heightened sensitivity plus the unexpected touch of a stranger.

Since you haven't been in a relationship yet, I would try to listen to your heart and try not the define yourself so quickly. Just know that many women struggle with this, and it's actually normal to find other women attractive! You might find that you are looking for a lasting relationship with a man, but sexually you may be bi-sexual. Who knows! Explore your feelings :)

Basically, sexuality is strange. Try not to over-think it and go with the flow :) You may want to explore, but just remember that you should never feel pressured or uncomfortable during sexual acts. Eventhough I think women are sexy, when I started to actually try to kiss a woman I felt like throwing up :/ Listen to your heart :) There is a HUGE difference for me between kissing a woman versus kissing a man! Your emotions will speak volumes :) Good luck!!
