I do my exercises in the bathroom all the time, and i turn the shower on just hot so that the room heats up and steams up, i thin kit helps, it would also help with breathing which is essential, because it clears the sinuses and the windpipe.
i stopped doind Penis Enlargement for a while because i couldn't find the time, so its gone down a bit, mostly because of my party lifestyle, but i did my exercises once in that same condition, and that night my new gf grabbed it and said "what the fuck?" lol, (in a good way) and we had sex until day broke and the birds sang.
