SEX! GUYS i need your input on this one!?

[Ebaby]

I have been seeing this guy for about 2 months now..we just officially became bf and gf like 3 days ago. I'm a virgin, hes got 8 girls under his belt and I was raised by my parents to wait until marriage and tht no guy will want to stay committed to a girl that gives it up.."why buy the cow if you can have the milk for free" type deal. Now we have gotten very close pretty much everytime weve fooled around but i keep thinking im going to feel so guilty and worthless afterwards bcuz i wont have tht very "special" thing tht my mom waited until marriage to give up (i do suspect my dad didnt) but i also dont want to do it for the wrong reasons. i want to feel good about it afterwards and not regret my first. Guys do you think less of girls if they give it up? Deep down would you rather have a virgin when you get married cuz its more exciting to wait? Would you break up with a girl just because she didnt want to have sex and wanted to wait until marriage? I'm 18 yrs old. my bf is 20. I have always found it easy to keep from having sex but with him its getting harder and harder and i just want to know if I'm making a good decision if i do sleep with him.
