Hi Dutchie: I agree with your basic sentiments and like many here, have asked similar questions and expressed similar thoughts in the past.
With respect to sexuality and sensuality, many religions repress these normally healthy features of humanity by using fear of lust, sin, wickedness, immorality, disease, Satan's influence, etc. Learning to enjoy sex and sensuality as one of many great aspects of being human takes time and maturity ... and when we have a religion interfere with this process for 10, 20, 30 or more years ... it takes more time, for some, to unlearn these false ideas, and relearn good and healthy expressions.
Discussing Sex on JWD: I think that some of this needs to be openly discussed. The most brilliant post I have every seen was made by Farkel on H20 regarding an old WTS article on masturbation. IN his extremely talented humorous style, Farkel demolished the WTS view and exposed their idiocy, and in the process helped a lot of viewers to take another look at sexuality.
Generational Mix is part of the problem: When I was a younger man, pre-JW days, I could engaged in Locker Room talk the same as any guy. I assume that girls have an equivalent of this. When we get older, we do not lose interest in sex, for that is about the last ting to go before we die. But we do learn that there is a time and place for everything. On an open forum like this, we have a broad variety of cultures, ages, and maturity levels ... some much more sensitive than others. It is this mix that clashes and makes it seem that some ex-JWs have gone bonkers with sex ... and some have ... but most of it is just the large mix of people.
Any Solution?: None, short of legalisticly detailed Forum Policies and heavy Moderation some other Fourms used to have. While it is disturbing to see some of the trash (Locker Room material) that gets posted ... the Forum for the most part does very well ... and most seem to keep a good balance.
