Welcome to the forum Mr. Stretch.
Do try, if you can, to post in the correct forum. Member Pics is a bit of a clue stick. Thanks.
It’s probably bad to smoke and masturbate at the same time, there’s a chance of dropage. It’s like having sex, always make sure your partner is below you and a bit kinky if you are smoking.
Certainly there are lots of smokers who have gained well. I don’t think it’s an issue as long as it doesn’t interfere with your erection quality.
Oh and check this out. You would probably have found it it you’d started with the Start Here thread in the Newbie Forum but as you missed the Newbie Forum entirely, I’m not surprised you missed this. It’s not called Newbie to be nasty or anything, it’s really full of good information for those starting out.
