penis not as thick when lying on my back.Why?

[gobig62]

When my girlfriend sits on me she notices that my penis is not as thick as it usualy is. Can someone explain why this is and what i can do about it. I have noticed that when i am standing or sitting up my penis is a lot thicker than when i am lying on my back. All advice will be appreciated.

is a pressure and erection strenght issue. When I'm not 100% aroused I experience the same but it is more an impression than a true loss in size.

Thanx Ironsteel, is there a solution to increase erection strength when lying on my back. I usually cannot get get my fingers to touch when when gripping my penis sitting up but this is not the case when lying down.

The difference should not be that noticeable. Perhaps when she is sitting on you she more loose due to her body position...I would belive this more than your penis is not as thick.

gravity.

Isn't it just like a woman to blame it on a man's dick...tell her to do some KEGELS!
