No worries Gooch. It's just girls talking trash, I hate it when they do that too and I'm a woman!
I am proof that their statement is not true. When Larry and I were with our g/f for the first time years ago, I had no idea what to do. I knew what I liked, but I also knew what I liked from the angle I'm going to naughty bits at. It's like everything was turned around backwards. It sounds silly, but we all have our little quirks and things that we like and dislike and I didn't want to do something our g/f wouldn't enjoy, luckily she had a blast.
If you want to be a great lover, you should learn all you can. Never assume you know all you need to. By being here, you're well on your way. My advice, that woman was speaking her opinion, and opinions are like asses, everyone's got one.
