The sutta you have kindly referred to is certainly a good support for seeing into the danger of sensual pleasures, very good. Thank you! Not the one I was thinking of, but really, that's ok. Yes, as you say, I should have started another thread. I guess I thought I was being economical by just tacking a "looking for source" request on to bodom's, but it could only lead to confusion. Won't do so again in the future.
