Up until I was about 19 or 20, I had maybe 1% interest in men and 200% interest in women.

Sex drive was strong, though with my erectile difficulties and general insecurities, I never went 'all the way'. Almost did on quite a few occasions but just wasn't working. Probably had a lot to do with performance anxiety. Anyway, then I came out as bisexual, admitting that I found some men attractive, but mostly just feminine men and I still wasn't too interested in actually getting involved with a guy.
My sex-drive was strong all the way up until I started HRT and then it got all wobbly. Still hasn't completely disappeared but it certainly changed. Between coming out and transitioning, my interest in men went up slightly but wasn't all that strong. But as my sense of womanhood blossomed and my male sex drive declined, I started noticing men more. I'd be at the gym and the pheromones would just slap me in the face as these buff guys would strut by me. My interest and desire sky-rocketed and I after a few months when I became passable and went full-time, I put myself out there and got a lot of positive response. So I've since talked with a whole lot of men, had various sexual experiences, and had a boyfriend that I lived with for a year.
I also used to perform on cam, and when I did, for a good part of it I was off my t-blocker to help that stuff out. My male drive went back up steadily and I was getting regular erections again but I saved the masturbation for that. But going back on to the t-blocker, it gradually went back down. I can't say it disappeared entirely though. For a long stretch of time it was all consistent. I'd maybe get horny once every other week. I use a vibrator now, and it feels great but it doesn't satisfy my female drive. When I get aroused now it doesn't translate down there. Instead my eyes glaze over, I get with the lip-biting, nipples get hard and sensitive, and I get waves of tingling all over. Sex fantasies have become more of a thing, and I never really want to watch porn anymore. I'd rather read a story because I can put myself into it. So that's another change. At my worst, I'm debilitatingly aroused and writhing around fantasizing and playing with my tits. Much different experience than it used to be, but unfortunately my vibe just doesn't satisfy it, and I either have to push it out of my mind or call someone up... I'm still not sure just how much it's linked to my cycle. After my first period I was crazy horny for an entire day. I couldn't concentrate at all. After that it was inconsistent. And lately, I was off my t-blocker for only a week and a half because of my doctor's appointment scheduling and running out, but I've been on it for 2-3 weeks again, and started prometrium (low dose first 15 days of the month), and the past week I've been super horny to the point that I couldn't hardly focus on anything. It's just started to calm down again, but it's been frustrating. I gotta say, I do kind of miss being able to get myself off and have my arousal evaporate immediately after. :/
Also, I will say that my sexual orientation has been frustrating as well. I still like women, but my sexual interest in other women has declined significantly. If I look at an attractive woman, I can still get aroused, but then I have trouble fantasizing about anything unless I imagine I've swapped my junk out for a more lesbian-friendly option.

I can see myself being romantic and having a relationship just fine, but when I think about sex, I think about men so much more. So my orientation hasn't exactly changed, I still lean towards straight, but I guess it transitioned along with me. I just wish I could pick sides though. Even though I lean one way or another at times, I'm still pansexual and I wish I wasn't...
