I think it depends on the male or female you are talking about if you are trying to guess who has the bigger ego. Or has the most fragile ego.

What I have found though is most often the ones who profess to be greatest lovers are in fact the worst.

One thing that will guarantee that sex will never occur; or never occur again; (with me) is someone who makes lovemaking a class or grades my performance.

My belief is great sex is and art form to be perfected over time by both partners. Idealy what starts out good just gets better with practice and praise rather than criticism.

Since I have rarely heard a man say any sex was all that bad I truely doubt less than perfection is going to be a serious problem on a first effort.

While it is not so common with younger people there are some who are have to worry about health issues other than just STD's. Sadly it is rarely anything that can't be worked out with good information/care from a qualified urologist or OBGYN but fear or embarrassment oftens prevents people from being knowledgeable.

What knocks me out are the number of men who get their sex education from smut magazines or prostitutes that will tell them whatever they want to hear and often baloney.

Hehe.
That cheered me up, man.

I don't know your real age, your real sex or your real original planet, but you're sweet.

And I say that without being gay whatsoever.
