Hey Kiki, I am not one to claim to have any edge on women more than the next guy.... but I've been around the block a couple hundred times...
The bottom line is this:
You are 20.
You are in college.
Girls are a distraction......... take that to the bank bro.
The best thing to do is plug as many as you can before one can catch you on the permanent side of things. Women want relationships, and sluts want sex... men want sex.. men want sluts. I wouldn't worry about a real relationship until I was older if I were you... it is way more fun and carries a lot less stress.
