I just took a look at the site and read some of the posts. I think it's a pretty good site. Susan answers in a very frank and honest manner.It all looks like good advice.
There is one thing...she will never know how it feels to be a man, or to orgasm like a man or exactly what it feels like afterward, what goes thru your head, or how it feels to get an erection. The same way that we guys will never know exactly how a woman feels. You can't get this info reading books.
So, maybe I helped you with a man's point of view. She might help you with medical reasons why.
