Quick Question With Boxers...

When you work out, you tear your muscles. Overnight they regrow adding more to compensate for the increased workload you are performing.
I figure it's that same with PE. I do jelquing and pumping and wear whitey tighties. If the penis is compressed in whitey tighties, perhaps it doesn't have any opportunity to regrow larger. In fact, if it's compressed, it may regrow smaller. This may explain why some people complain of this. Any information would be very helpful...

Even though you may have a valid point here, i think this is not the case. Personally i wear boxers anyway (i find them more comfortable, and you hang lower). i think PE works on some of the same principles as musle regeneration, but i thought actual PEing was the stretching of blood vessels, the tunica etc.
Anyway you may be correct.
Hope my opinion helped.
Goodluck PEing

I don't think it would regrow smaller. However, there are several reasons I switched to boxers. First, briefs or tighties as you say lower your sperm count because your testicles get too hot because they cannot lower themselves to cool off. Your testicles need to maintain a correct temperature. Also, if you get into massaging your testicles and doing a power stretch (stretching the skin between the penis and testicles) it will cause the testicles to hang better which will also cause your penis to have a more hung appearance. Additionally your penis will get used to hanging more in boxers. I think it may effect the flaccid appearance of your penis. Finally, if you want you can walk around with a softy or half hard on and it really can get some attention sometimes.
