while laying down in my bed and watching 1 of my many dvd's i noticed that as i orgasmed, my junk (i.e. cock -- LOLz) got quite hard and got VERY sensitive as i ejaculated.

comparing that while say i am sitting on the floor and watching another dvd, my cock doesn;t get as rigid/hard.

anyone here care to share or give insight why this is so?

other than being a messy cleanup, the orgasm i had whilst on my bed was quite good and fulfilling.

tia!
