I have not given or received but I can’t say I would have objections either way. It does seem interestingly taboo. And of course the brain is one of the most powerful sex organs.
I did see one night on an old late night TV show called “Talk Sex with Sue Johnson” when somebody called and wanted to know if peeing into her vagina by her boyfriend would be a problem.
Sue responded somewhat matter of factly, as she always did, that it probably should be OK, unless maybe the guy had any type of urinary infection. My thought was, unless a condom was involved, the semen would possibly be contaminated anyway and with a condom peeing probably would not work so well.
Yep … that one does NOT sound so interesting.
