Honestly?
A random woman, who is married, has come back to mine for some random sex?
And I assume she is attractive enough for me to take back home?
Honestly, yes. I would have sex with her and never see her again. This is her problem, not mine.
I've noticed a lot of people were saying they wouldn't pursue a relationship with this married person, but that's not the question. Of course I wouldn't date a cheater, but if they're attractive, I wouldn't care one way or another.
Next day, she leaves, we don't see each other again. Sorted.
