If yes, a reasonable reason will be appreciated.
Men are genetically wired to be more sexual then women, this harkens back to our tribal days, when men were hunters and women were gatherers. As men went out to perform dangerous tasks the odds of all of the men returning were slim, So, in order to have a strong and successful tribe the men were geared to ready in an instant no matter what the situation, where the women were more casual and laid back, this applied to sex too. This is also why men like younger women (breeding) why men are attracted to threesomes (more women then men in the tribe) etc etc. In regards to your question, for ancient man (as it is today) sex also proved to be tranquilizer helping them to relax after a difficult day (what else did neanderthals have to do for entertainment anyway?) Most of today's sexual behavior is left over instinct from our ancient ancestors, however, unlike them, we have developed finer skills and are not solely reliant on instinct. With the ability to reason so we should be able to curb our emotions why we dont, well that's probably a question for another day. =)
yes. They have more androgens then women. Also, from an evolutionary perspective, a man can increase his liklihood of passing on his genes by having more sex with more women. Once a woman is pregnant, she can have as much sex as she like and it will do nothing to increase the amount of offspring she has. Unless maybe she is one of those strange people with more than one uterus. But thats not the point.
It does vary between people though. In general I would say yes but I know many exceptions to this.
Theres an interesting article on Pubmed Central titled "Sex Differences in Response to Visual Sexual Stimuli: A Review". It sort of touches on this subject. Of course nothing in science is 100% set in stone, but I found it to be a decent read. You may want to check it out.
When men are young...teens and 20's, even into their 30's men are more sexual than women. Ah.... but once women have hit their late 30's thru their 50's they beat men hands down.
honestly, i believe males and females are 'almost' at par. but females just 'hide' it more if you know what i mean. maybe there's also some hormones playing in there or something..
Males tend to be more open while women are tend to keep it to themselves!
idk.. but if im in the mood im in the mood
