I must say, when a chick goes down on you and she does that.. the orgasm you get as a dude is much more intense.
To the OP:
I was in the same boat as you about a year ago. I was 22 and a virgin. I decided enough was enough and did some research on the net. If you can, go look for an ebook series by David DeAngelo. Most torrent sites will have it.
He teaches you how to build up confidence, how to read body language etc. I will attest to his methods. After reading his material, I decided to go to a pub and practice what I had learned. Met a chick there, flirted etc. We hooked up that night, exchanged numbers. 4 days after that I had my first lay. We dated for 3 months then she moved outta town.
After that, I met this other girl at a friends birthday party. We conversed for a month or so over mxit and facebook. Eventually we made a date and went out. That night I laid her. We ended up being together for a year until she broke up with me 2 months ago.
Was I upset? Sure. But life goes on.
I then met this other girl through a mutual friend. Did the same tactics as what DD teaches. Few days later I laid her. Now we're just friends. Dunno if it's with benefits or not. Buuuut I don't care, I'm always on the prowl. Currently working on another chick lol.
Also, as someone suggested. Get experience, I didn't wtf I was doing when I first started having sex. My first and second had to show and tell me what to do and how to please them. Invaluable information you will always need. Always, always make sure the woman orgasms first as well. It's just better that way.
