Well, in your age I was also virgin, it is nothing dramatic, but fuckin is good so try to do something with it. If you think you don't look good than there are some things you can do that will help you looking better, but you are doing mostly for yourself, because for girls everything you need is self confidence. No matter how you gain it, but if you look better, you feel better about yourself and that is great for chicks. For me it was these easy steps that worked perfectly:
1. sunbathing - every guy looks much better tanned, even the ugly ones
2. working out - it is not as hard as you might think and helps a lot with self confidence
3. contact - be in contact with as many girls as you can, use internet, chats, dating sites all this BE ACTIVE!!
4. ******* - if you are not too much ***** it always helps.. two ***** people of opposite sex alone.. almost every time it ends in bed

5. (optional) pay a hooker for the first time, it really doesn't matter who do you fuck for first time as long as she is girl
I don't say it works for everyone, but for me it was like magic, especially point 3.
