ADS for newbies

I’m in my 3rd week of PEing. I have known about it forever but never dedicated myself to it until recently when my ex-gf broke up with me, then I found out she cheated on me with numerous fellas. I can’t help but think I wasn’t satisfying her. But regardless of all that, I want a big cock for the next girl I’m with so that’s one less reason for her to cheat or leave.

OK on to the point, I have a small flaccid, and I’d like that to be larger. Would it be all right to ADS (all day stretch) as a newbie? I want to use the wrist wrap from Wal-Mart. Also, does this effect erect length as well?
