In general I am fine with being objectified and even fetishized to a certain degree. However when I've ended up with people who have completely zoomed in on my pre-op parts while being very disrespectful by not taking no for an answer (cause I don't like having anything put inside me there, but sometimes being overly clear about that isn't enough, apparently), just isn't the way to turn me on.
I mean, I can't deny that I like it when others are fascinated and kinda bewildered by the fact that I'm trans and how I look (makes me feel extraordinary and special, I guess, so it's nice for my huge ego), even if that's the only reason they are attracted to me at all, as long as they're not getting rapey with me. Most people I've been with have been one night stands, so there was no emotional connection between us which is how I like it too.
So, I don't actually mind whatever reasons or mindsets people I'm with have or don't have, it's when/if they cross my boundaries or even assault me that I have an issue with. Basically my point is that for me it's pretty much anything goes, but damn you if you don't stop when I clearly say no. However, at this point I don't really get all that upset when such things happen to me anymore. I've become desensitised somehow and brush it off within days or just minutes after. I didn't think I could get used to that kind of thing, but oh well. I move on from such experiences quite easily these days, but I still know it's effed up.
I've only been with men, by the way. Most of them bisexual, a few straight or bicurious, one gay, some I don't know how they identified. They've been of all ages ranging from 20-something to 60-something. Most of them have been a delight to be around, just a few that were bad apples.
