Having sex with close relatives is generally frowned upon, and unwise genetically speaking.
Ordinary people have sex with people they love, or like, or at least fancy for a night.
Ordinary people take it for granted that everyone else has had sex now and then sometime after age 20. People in general are WAY too much engaged in their own lives, to bother much about other people’s lives.*
You don’t need a girlfriend to have sex; people have casual sex with people they like now and then.
I probably had sex regularly when I was 19 too, as me and my now-husband got together when we were 18. I would NOT have agreed to have sex with just anyone back then, just because I was already having sex regularly, and nor would I have looked kindly on my husband having sex with just anyone.
I was having lunch with my then-boss regularly too, but I would NOT have agreed to have lunch with just anyone, either.
Why don’t you offer yourself as a virgin for a gay man to take? You wouldn’t have to do much…
YES, IT REALLY IS THAT MUCH OF A DIFFERENCE WHO YOU HAVE SEX WITH, NINCOMPOOP!
* Unless people are actually having troubles, of course. Most people have empathy for stuff like getting sacked, getting robbed, getting raped, the spouse being unfaithful, having a debilitating or potentially deadly disease, etc. Not having sex is something you have to deal with on your own, BY MASTURBATING, dolt. That’s partly what it’s for.
