Sexually Repressed? Left My Religion?

[believeinpeace]

I recently left my faith (gradually over the past two years). I'm trying to integrate myself into normal society but that it isn't easy. The hardest aspect is relationship stuff. I'm pretty clueless, especially about sex. To put it into perspective - I was taught that premarital sex is a sin. I was 17 the first time that I saw pornography, and 19 was the first and last time that I kissed a girl. Now, I am almost 22. Two years of college have really helped, even though I lived off campus. Most of my friends and immediate family still are close with me, though not all. Anyone who has had similiar experiances will understand. I've been trying to have a relationship for a while, but because i am so awkward about physical stuff, things keep getting messed up. The last girl that I asked out (it took a long time) broke up with me because of this. I really want a normal relationship because it does suck to be alone. I am having a really hard time getting over her. Any advice would be great.
What would I gain by making this up?
To all the people that tell me to return to god - stop. I respect your faith, but I chose my path.
