"Please help! I always feel dirty after the deed"

From a female blog reader:

I am a 21 year old graduate, am a pretty girl and i have many suitors the problem is i tend to give up sex too quickly. This is a problem because after the sex i feel so dirty and guilty even though most of my partners don’t leave and want to build a relationship i don’t feel the same way because i feel like i sold myself short. Have really tried to be celibate and stay away from sex but i find it very hard. I have prayed, set goals even went as far as staying off men but nothing works. Please i need advice thank you
