just keep focusing on yourself, girls are a lot of baggage from my limited years of experience, keep close female friends around you for your male needs, but don't wife them all up, we too young bro, we gotta build ourselves up and become successful

I've had a couple of long term relationships and my current partner is the one I probably see myself marrying. She's my best friend and we were friends before we started dating. It always helps to know you'd be friends even if the sex wasn't on the table, but in a proper relationship, sex is never off the table.

 

In terms of moving on, time. Keep yourself active and if you want to jump into bed with someone, go for it. Don't be hard on yourself about anything.
