This is one of those eternal questions men ask themselves in the, usually, vain attempt to find women for casual sex. However, the answer is simple. Women looking for in men a series of physical traits that are largely common and determined at genetic level and also certain features that vary from one person to another.
The physical side is rather simple since physical beauty is hard-coded in our genes. The tall, handsome man with a deep voice and a style that is practically oozing virility is guaranteed to be a hit with most women. His physical side is good. However, if he says something stupid every time he opens his trap, then it’s quite clear he would have to make do with women who either do not notice or do not care.
But almost any lack of luster on the physical side can be made up by another skill. A lot of women appreciate men who know how to carry an intelligent conversation and have good manners.
However
Single or swingers women are not interested in anything but sex with as many interesting partners as they can get their hands on. They are looking for men with those certain features-talent in oral sex, or the ability to give multiply orgasm for any lady. Also some of the women looking for confidence in men. Confidence is one of the keys to a successful sex life and is considered by many swingers women to be the most important feature in a man, aside from the physical endowment.
Swinger women simply like big penises, but a penis that is too big tends to scare women away.
Despite sound bites such as size does not matter, or the key is how you use it, a bigger penis makes the job much easier for the man and brings more pleasure to his sex partner.
