I'm a 25 year old guy and I went through a little bit of questioning myself. Though when I think back I'm pretty sure I put it off from highschool. I find that for me I find women romantically, sexually, and physically attractive however I also find that there are certain male aspects to a lesser degree physically and sexually attractive however I haven't yet found any romantically attractive.

I'd suggest visiting /r/bisexual or /r/pansexual (apparently there is also a /r/pansexualteens subreddit as well). You don't even have to post if you aren't comfortable with that.. It's likely somewhere on there someone has posted about questioning or has just come out.

As for me. What I learned is sexuality is not something that is really defined very well. There was this really cool image on the pansexual sub that made me feel a lot better. Sadly I don't think it made the trip from my old harddrive. It was pretty much a graph chart thing that there is a lot of betweens. There is a lot more then straight, bi, and gay.

>Maybe this has something to do with not having a father figure in my life? Has that made me feminine or something?

I'm not a psychologist so I can't say that isn't the case. All's I can say is for me I had a pretty strong male figure in my life and while I don't project being feminine in real life on a day to day basis I've been told by some close friends that I have a fairly feminine personality. I've also been mistaken as a woman online many times. (I've even been hit on by a lesbian who would not believe I wasn't a woman until I had a mic)

Really my best advice to you is to not worry about it. Just wait and let what comes naturally come. If you find yourself having feelings for a guy, then go and do that. I wouldn't really worry about your parents until it's really relevant to tell them. Grant it I'm not a teen so take that how you will.
