How can I have a stronger penis on my back? -

I have a very big penis and I can get it hard as steel when I jack off sitting in a chair cause thats mainly how I jack off,and it feels better to me sitting down but when I m on my back I can t stay hard at all cause it s so heavy and it just falls .So when a woman wants to ride me I can t stay hard but when I m on top or doing it doggy I m hard as steel,but just not on my back.What could the problem be?

why would you want a penis on your back?

Well look 4 help, yeah I know its a bit shameful but u must know wat happens. I think tat is bcause of the angle ofd ur back. when you have it 180° it is forced to go with the torso, but when in 80°- 130°, I think it goes erect to the front bcause ots no longer forced onto ur body. Its just a theory, but please go to the doc. Good luckk!!!!!!!!!!! PS- With quot;like Whoaquot; do you mean the song?

Majorexagerating, it s serious, very much in danger of falling off, seek help fast.

well you can try to play with ur balls or something

Maybe your just a guy who likes to dominate in the bedroom.
