I suspect the "thrill" and awesome sex experience in the A comes from being with someone who is NOT your spouse. And in MLC, a spouse you have come to HATE (yes, we have all gotten the spew to know we are LOATHED).
So, though you look at the OP and say "eeeewwww...icky"...there is some thrill there....the thrill that it is not you.
I also suspect that a lot in the "great sex" department, if it truly IS better sex, is b/c it comes with a lot of anonymity...so you're more adventurous, free and all that stuff.
End point...you're not YOU in MLC. So, everything is distorted, for good or bad.
