It seems to me that many attractive women in my age range already have a boyfriend, a fiancé, or in a few cases even a husband! The pool of smart, good-looking women with good personalities (as opposed to "bitchy"), worthwhile interests, and ability to plan for the future are a scarce resource; and there is considerable competition for them. As it is, I happen to have a very high sex drive, so I've also been looking for reasonably physically attractive women for a purely sexual get-together; again, demand is higher than supply.
It seems to me that, as I have been trying to attract women without success, the attendant frustration has made me increasingly aggressive, forceful, and uncompromising in particular towards the competition: other men. I have recently read this article, which confirms my suspicion. My theory is that sexual frustration increases testosterone circulation, which increases the tendency towards competitive behaviors so as to get a mate.
Some ways this anticompetitive aggression may manifest itself are running slow drivers off the highway, threatening the male friends of a potential mate, attacking the reputation of competitors, and using (preemptive) physical force to deter competitors (I am not implying I do all these things). Also, this sexual frustration leads to a preference for women showing signs of ready sexual availability: revealing clothes, seductive behavior, and possibly reputation for promiscuity.
Other ways this sexual frustration may manifest itself are pursuing women for a longer period of time, relative imperviousness to risk, ambitiousness (to acquire the wealth and other resources that make a man more desirable to women), and resorting to tricks to put women in sexual positions (e.g., posing as a modeling photographer for "swimsuits" or "lingerie" and then perhaps prodding the woman to take off all her clothes because the nude pictures might "pay better").
Anyone else notice this?
