Why do people always assume we event want it up the ass? Like.. do people not get it or something? Some women like it, some women think it's discussing and would never try it... you know just like regular women.
If a guy I was dating just tried to put it in my butthole without talking about it first, I'd be the last he'd ever see of me. Yet this is some how acceptable from the POV of most men just because a woman is trans.
I'm really just sharing my frustration that a guy who figures out what I actually want him to do without hints is quite rare, while I don't expect that it's really nice when a guy has never heard of women like me before and so has no pre-conceived ideas about our bodies or how they work.
We are all different. Unfortunately internet porn has made out that we like certain things in bed.. look at react a certain way... when in reality if we've been on homrones for any length of time (15 years in my case)... the answer is "not necessarily"
Your post is not clear whether you're apprehensive about it or she is, so I don't want to be taken as telling you off - I'm more intending to share the awareness that the common assumption of "that's really the only place I can put it" is actually false... but that's kind of ... you'll have to ask her.
In other words.. you should be asking her this question not asking online - it's much like asking your non trans woman gf to have anal sex with you?
to be blunt, our anuses are not physiologically different from non trans women.. yet some men, not say you do seem to think that trans women are some sort of magic anal sex machines.
I'm sorry i'm not more help in terms of more about what you should do. I suspect the are other trans women out there who are more open about discussing the wide range of possible bedroom activities for us, But I prefer to keep discussion of what I like in bed & what is / is not possible with this body strictly to people I'm actually sleeping with and feel that any one else wanting to know is kind of icky.
I'm still in therapy working on being comfortable ever having sex again because of how badly both men & women have treated me around feeling entitled to my body without giving a seconds thought to consent because i'm trans so I'm probably not the best advice giver. Sorry!)
Note: for those unable to determine the obvious I'm a bi trans woman, so I think that makes me qualified to talk about how to deal with having sex with us :)
