yes I do think its both genetic and circumstances such as masturbation.
Too bad we do not have many people, if not we can conduct a survey ...
taking into consideration from anything from what age men started to jerk off, to type of underwears, to how active are you in sports ... ect...
If only our forum has 60 000 people !! THen we can conduct a survey that might be a bit accurate! Maybe the survey has been done ? |
