Even though I've only poked a foot out of the closet so far, of those who know there have been a few that have suddenly became very interested in my sexuality, what I am attracted to, what I consider my sexual orientation to be, and have even been asked by some if they can see my vagina after vaginoplasty. This includes the dad of one of my friends, who turns into the stereotype of an old creeper around some of his daughter's friends (at least for me she got onto him about it, which she normally doesn't do when her dad becomes that creepy old guy). This has mostly been men, but a couple of women have been this way. From my mom I have heard her ask, when she was talking about a MtF woman she used to work with years ago, "if she dates guys is she gay, but if she dates women is she a lezzy?" And then recently I have heard that I should just have sex with gay men since that's what I am.
Public restroom use is another issue that plagues the lives of transsexuals. Though restrooms, especially women's, have stalls and you can't get much of a peek without looking suspicious, people are very concerned about this and every once in awhile a MtF woman will make the news for being charged with using the women's restroom.
And even though it seems odd that this would happen, because people tend be rather nosy about the sexuality of transsexuals, many men consider it an attack on their masculinity to have sex with a transwoman.
