Good sex is honestly a toss up, I've had great sex in horrible relationships and bad sex in great relationships. I understand being in love with someone enhances it but love is a feeling which is impossible to sustain permanently

I've not found loving someone to help with the quality of the sex all that much. Maybe they just didn't love me back or something. The crazy one was always great and was the only one who wanted it as often as I did but the rest of that relationship was a mess.

Have you actually tried taking unrepentant time off, where you have no work or social obligations, and grabbing unhealthy snacks and drinks, curling up with a good game, and zoning out of reality for hours or days at a time?

Sex is nice and all, and we're hard wired to like it more than most activities, but it does not hold a single candle to unrepentant free time when you're not used to said free time.
