Use to masterbate 2 or 3 times I day one day I didn't want to do it anymore I think it would smell or something and I didn't want anyone to know I did it. I did it dry and I also got worried it made it smaller cuz it use to be 4 inches then after 3 or 4 months it went down to 3.5 inches so I got scared by that too. Is it ok just to stop
The choice is up to you. But as along as you shower regularly, you are not going to smell and no one is going to know that you do it (even considering that about 90% of all males do). Masturbation is compltely safe and won't have any affect on the size of your penis. Chances are that the one time you just had a stronger erection, or you measured differently.
