2 questions for the forum:

1, I've enjoyed the opportunity I've had to speak one on one with Maxout recently. Something he mentioned as a habit he has adopted got me to doing more research, and I've been icing my testicles with a gel pack placed between my underwear and pants for 15-20 minutes 3 x's a day for the last couple of days. This is said to promote testosterone and hormonal production in the testes.
Before I get too far along with this practice, I just want to know if anyone can think of any reason this should NOT be practiced by those of us in our situation?

2, since getting back to a more normal sexual routine lately, I've been a little paranoid about lubes. I have a variety that I've accumulated last couple of years, but would really like to know if there are any highly recommended brands/types for PFS guys? Ones that obviously dont contain any offending ingredients, or possibly beneficial to our situation? Or, at the very least, neutral?

Thanks as always...
