Sorry, I was reacting outside the context of the thread. My apologies. Yes, I am a bit sensitive to being preached at, especially by people who think I should simply divorce someone when the sex situation can't be resolved, as if that mattered more than anything else. Or by those who claim that if the sex doesn't work, the whole relationship must somehow be dysfunctional, or as a former poster on this forum told me, my marriage is a "sham".
MrBond, I agree with all of your points. In my case, what I do has practically zero chance of STDs. Which means it's pretty limited.
I'll admit I don't have any recent memory of the kind of sex that's "an expression of love".
