So I saw this post on Tumblr , so I don't know the accuracy, but it said that a lot of trans people don't know that hormones affect sex and the need for protection. I'd never heard this before and I can't find anything about it from Google, does anyone know about this?
Huh? The phrase "hormones affect sex and the need for protection" appear to be two completely different issues. I'm not sure what you're asking.
"How many trans*people don't understand that hormones change the way sex works and the need for protection?" Was the only sentence on it, in a post about sex education.
I don't think it does? It matters what parts there are... And use protection even if doctors perfected those parts.
I thought that hormones pretty much destroy the chance of pregnancy if on them long enough (not sure about STDs)
Hormones don't change the way that sex works from a mechanical perspective. They most definitely change drive, attraction, and can affect arousal and orgasm. I have no idea what they're talking about with regard to the need for protection.
I think they are talking about 2 different things. First, Transpeople may have misconception about how hormone and sex, such as hormone will not change your sexual orientation. And the second thing about protection is that, some transpeople after SRS may assume that they no longer need to have protection because they can't have a child from having sex, forgetting that STD is still a problem.
Yes, STIs are still a problem after SRS as they are transmitted through bodily fluids(mainly semen and vaginal fluid, but it also depends on STI itself). No matter whether its viral or bacterial. So protection is a must in any case. Eg: you can get infected with chlamydia through contact of genitals without penetration, orgasm or ejaculation.
