Sexual incompatibility may mean many things. Perhaps one likes oral sex and the other does not want to give it. It could be that, due to past repressive upbringing, a person only wants and performs "missionary". The level of dissatisfaction may bring strain into a marriage or relationship. For some people, it takes an elaborate session of foreplay to get it up and going. If you need some pom-poms or a strip-tease to get your rocks off, it should be worked out between the individuals. If it can't be worked out, then there is some sexual incompatibility.
Still, that's something that should be worked out privately and is no one else's business. If one strays after years of not getting what he or she wants, a paid service will probably give it to them. Sexual habits are hard to break. We criticize the controls the JWs have placed on us regarding sex and most of us agree that it is none of their business what a couple does in private. I don't see why criticize Lloyd's actions, even if we don't agree with them. It was a private matter that seems to me was outed by someone else out of spite. There was no need or urgency to reveal his personal foibles.
For Lloyd and for his marriage to continue, something has to change. But if it doesn't, life can go on in a different manner and with somebody else who is more compatible. I think it's easy for some of us to make determinations about his conduct without understanding the conditioning and pressures an individual goes may have experienced.
