Fun stuff... I recall having to forceably push girls out of my lap because I didn't want to be with them. Yes some guys have standards... no it's not a shallow thing... these girls looked good I just didn't want any reason to be in a relationship with them... too much upkeep/ baggage. To this day I don't regret it and my standards lead me to an awesome gamer girl that I married.
TLDR: Advice is don't regret the past; learn from it and forge ahead.
