As the majority of my readers are female, they may not know about a serious male problem, known by a couple of names, one being blue balls and the other, well I forget, but let us call it the unrequited passion of love.
The cause is prolonged sexual arousal without release. It is horrible. It manifests itself as a pain deep in the male guts that comes from the testicles. The trouble is that men can become very aroused just by walking along the street and seeing women or men and thinking about having sex with them. Men think about sex way too much for their own good. You think your man doesn't? Don't be mistaken, don't be misled, your bloke thinks about sex, way too much for his head.
Ideally a bit of jiggity jig or rumpy pumpy will cure the problem but a hand held release also gives a cure or time will take care of the problem in the manner of pubescent lads. Ok, it is nothing like the pain of childbirth, perhaps just 90%.
