A girl I was banging for awhile who had a boyfriend would beg me to nut in her. She wasn’t on BC, but tracked her cycle (as did I). When it was presumably safe, I would and she loved it.
Sometimes in the heat of the moment when we both knew it wasn’t a “safe” part of her cycle, she would still beg, but I knew better and would muster the self-control to pull out.
It was usually the fertile time of month that she came around looking for it anyway, so I had to be careful
The craziest thing? I found out she made her boyfriend wear a condom even though they had been dating for years. She never once mentioned the “c” word to me.
