They are only good at it when they are totally relaxed with you. Not only that, you have to be totally relaxed. Ive tried sitting down with one and showing her some techniques I found via google. No luck there, I havent felt any difference before or after.
Different girl, we're into each other, shes relaxed, Im relaxed, both drunk. It was amazing.
Down side to this is that you dont last as long when you are relaxed completely. I dont know how to tell you what I mean by relaxed completely, I guess not focusing on your performance and other things.
