Of penis length, if in return, you could (immediately) have...

A.) a totally phenomenal ass
Nah, my ass is pretty good already.

B.) a super HOT torso: nice big pecs and well defined abs
Could have that if I wasn't so lazy.

C.) bigger balls
You get those from not jerking off

D.) taller stature by at least 3"
I am comfortable with my 6 foot stature

E.) ability to shoot a super big load
All I have to do is not jerk off.

F.) ability to be genuinely multi-orgasmic or just have more intense orgasms than you do now
Hmmm, that one is interesting. I like my orgasms, but I would be concerned that I would lose my stamina.
