I've only been on T for a month so I can't really say what is going to happen to me eventually, but my sex drive has definitely increased dramatically to the point where I am almost desperate to get off once I get started. Since the stakes somehow seem higher if I don't get off, I guess I am more willing to go to any lengths to make it happen. I can see how that would make me more open to experimentation or doing stuff I wouldn't have been comfortable with before if it meant I was able to have an orgasm/a better one. I think maybe before T we tend to have a take it or leave it attitude towards sex and on T we're more willing to work for it you know...Do some weird stuff...
And before T, I think dysphoria would often overshadow my need for sex and now, especially since T has made me less dysphoric, my sexual desire almost always cancels out my dysphoria. I think certainly if I passed I would be willing to do certain things I would have considered emasculating before. I'm not into dudes and hopefully it stays that way though haha. Not that there is anything wrong with LIKING dudes, just that I am not prepared mentally for a sexual orientation shift.
Now that I think about it, I think as of now T has increased my attraction to women and not done much to my attraction to men. I think there's always been a smidge of admiration there, and not just jealousy, but so far it hasn't gone beyond that since starting T. And really, my attraction towards women has been almost entirely directed at my girlfriend since she is always around and usually willing. I haven't like been drooling over every woman I see. It would be interesting to see how I felt if I didn't have a steady sexual partner though.
