Hi!
I'm single and haven't had sex yet, but there's a question that's been on my mind for a while. Is having sex without any form of protection okay under any circumstances? Like, if both people were getting std tests regularly and pregnancy wasn't an issue (for example , since i'm amab, If I had gotten a vasectomy), could I have vaginal sex "raw"? What about oral and anal?
Thanks,
Aspin
