The first is when I start to get hard my penis becomes more sensitive to the touchand any light touch to the penis will bring a pleasing shiver right up my spine. This is where I recieve most of the pleasurable sensations.
At the second stage of arousel, I feel that my penis gets more harder and that the sensations are more pleasurable. It is when the head of my penis starts to throb and this sensation is like when you jam a finger though it is a pleasurable throb. I can also feel my balls being pulled up tightly towards my body. This is the stage that I spend most of the time at. It is probably the most pleasurable stage as I can control myself and can stop recieving direct pleasure and concentrate on pleasing the girl.
At the third stage I tend to lose my self and get the feeling that I must have an orgasm. When I am very near to an orgasm, I can feel my arms and legs tense up. Sometimes I will hold my braeth until I orgasm though I have recently been concentrating on ensuring that I breath during this time. If the sex has been going on for a long time, I will usually start to release pre cum during this time.
As I am very near the point of orgasm, I can feel at the base of my penis fill up with semen. The most intense pleasure I recieve is just the second before I orgasm and when I orgasm I can feel the semen shooting out of the tip of my penis. For me, the actual orgasm sensation is not as pleasurable as that second just before the orgasm and I actually find that an orgasm is more of a release of tension than actual ecstasy. During a typical orgasm, I release six loads of semen though if the orgasm is an intense one, I can have up to ten aftershocks which usually releases only a small amount of semen.
After orgasm my penis is too sensitive to touch and I usually lose my erection very quickly. If I am in the mood I can regain my erection within ten minutes. However on a couple of occassions I have been able to sustain an erection after an orgasm though it was too sensitive to touch for around ten minutes.
I have found it hard to describe my experience though I think this covers most of what occures to me.
