But I think that the most detrimental things about sex for a guy is often having to spend so much money, time, and effort on a broad before the sex act, and having to deal with the whining and nagging about "commitment" and other pointless drivel after the fact...
LOL! That's why a guys test levels go down afterwards. He wakes up to an empty wallet and a girl that thinks they are getting married after the first nite in bed...
