Traction and body posture

[Juan]

I'm trying to start traction with the pmp.

I notice that my body posture affects to the traction.
If I'm layed down in the bed I can stretch much easily than if I'm stand up. Like if the penis while layed down was more flaccid and flexible.

So I usually put the pmp layed down in the bed and stretch to a certain tension. But Then If I stand up, is like if my penis gets less flexible, harder and that tension is too much.

If i put the pmp stand up i can not reach such length of tension.
