At the end of the day, it's a matter of what you're comfortable with and what works for your relationship. I've dated girls who've gone to the club a lot as well as girls who hate going to the club, I don't think it's necessarily affected our relationship.....Honestly it's never been a problem in any of my relationships.....but I noticed that when you try to tell girls what they can't do in a relationship with you, it pushes them to do it.
I'm Dj and get hoes just for showing up to work.....I'm not worried about her grinding on some nikka.
If you're not comfortable with a joint going to the club all the time, save yourself the trouble and don't date her. I'm not really a club dude myself, I just happen to like music but yeah find someone you're compatible with.
