I followed the thread of your discussion with azimorane however it seems to me that your two friends had many problems together, you maintain that it is mainly due to a sex problem but it may also have been another previous problem and therefore they were both subject to a premature end. Sex addiction exists and no one questions it but it can lead to a tragic and less obvious end. However, if his two friends died, it was clear that they had major psychological problems and the fact that they also fell into alcoholism and drugs confirms it. Everything cannot be blamed on just being addicted to compulsive sex.
