Why risk prostrate health?
You need to come/cum at least 3 times per week to keep prostrate cleaned out...just consider it exercise....
Every week, for your whole life...from the time you are of age...
Then when you are 70 you wont have prostrate problems...
Men over 40 ? Better keep wacking, or you will end with a high PSA number...
I guarantee that no doctors have prostrate problems, cause they know...
BTW... My PSA number is .7 [point seven] normal for my age is 4... four...
Don't do damage... wack away...
