I don't have any complaints personally, but as a good observer of people, I would point out a simple fact:
The neural pathways that govern orgasm do not fully develop in either men or women until puberty.
In a repressive environment where adolescents are taught that it's a sin to touch themselves and that they should pray for forgiveness after performing simple acts of hygiene, normal development can be arrested or stunted.
It's not a problem for men nearly as much as it is a problem for women. Male physiology does not leave JW males much choice, but it's entirely possible for a JW female to enter into a sexual relationship (i.e. Marriage) having never experienced a single orgasm in her life and with only vague ideas of how to get there.
Worse, if she's waited much past the bloom of youth to get married, there is a chance she may never be able to get there or always have problems.
So yeah. I'd say the JW's have messed up a lot of people's adult lives.
