For the last 2 years i wasted my time on a guy who hasn't commit in a LONG time (we were together for a short period of time 2 years ago), used me, etc....to make a long story short, i dropped his sorry butt, and have since then started dating a new guy

2 part question:
There is this guy i've been dating who is interested in me, but now it seems like i think every guy is out to use me like my ex did. How Can i get over feeling this way, and is there anyting i can look for ahead of time to keep away from guys like my ex?


Also, I'm so used to how my did things...kissed, cuddled, etc. I've kissed this new guy twice, and it is so different. The last guy was SO aggressive, and that's what i've been used to. One thing me and my ex had was great physical chemisty. Now this new guy is more shy, and completly different. I lost my virginity to my ex, would this have anything to do with the way i'm feeling. Will this pass as i get to know this new guy more? Or is this a sign that we're not right together?
