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

A.) a totally phenomenal ass
My ass is already phenomenal, so that is irrelevant.

B.) a super HOT torso: nice big pecs and well defined abs
I'd say I am happy with my body right now. I work out a lot, take some suppliments. I go from a 33 waist up to a 40 chest. I like it. And even if I wanted more, I'd just keep working out instead of trading precious legnth.

C.) bigger balls
Mine are already bigger than average, but I always wanted to know what it would be like to have horse balls for a day

D.) taller stature by at least 3"
Hell no, I am happy at 6 foot 1.

E.) ability to shoot a super big load
I already shoot crazy loads, so no.

F.) ability to be genuinely multi-orgasmic or just have more intense orgasms than you do now
I am multi-orgasmic, but I would LOVE for them to be more intense. My first one is intense, but the other ones could be better. I'm not sure though.
