My wife confessed to having sex with a stranger when we were in grad school. We weren't married at that time but we'd been together for a couple years. The revelation happened during foreplay talk when I admitted to sleeping with an ex-gf a few months prior. My wife didn't seem upset but proceeded to tell me about a recent drive to Mexico with her entomology class. She spent a few hours in the field with a local beekeeper. She said he was very sexy and flirted with her a lot. Around the time she was to leave they went to a supply shed and had sex. No condom or anything. She's not usually impulsive like that so it was surprising to hear. She wasn't on birth control at that time so for her to have unprotected sex meant she wanted it badly. Btw, I asked if they used protection but later realized it was a stupid question.Would love to hear more about this. Why do you think your wife was impulsive on this occasion?
