if you want to prevent stretch marks, this is possible.. just take extra skin care along with your Penis Enlargement career. use cocoa butter, lotions.. etc.
i don't want stretch marks, but i don't care if they appear either.
if a chick notices, you can make up some BS that your penis went through rapid growth in your teens, and alas, the stretch marks...
i havn't gained all that much, but i havn't noticed any so far. i use lubriderm lotion down there.
