As a pleasure seeker, is it possible to prevent the pain that comes after sex/love?

I love sex and l always desire to learn more and practie in differenf ways.But when I find a good partner I find he withdraws when it starts to get interesting. Then the pleasure becomes pain. According to Lembke of Dopamine Nation this is normal, as the brain balances itself after dopamine spikes with dopamine withdrawals.

As a lover of sex, how can I avoid this? Please don't tell me to find 'true love' That it not something you can control. But there might be a way to approach pleasure/ sex/ orgasm that can maximize the pleasure over time and minimize the pain.

One clue, pleasure from effort ( eg. As in the pleasure derived from a workout or a job well done) delivers a secondary dopamine spike which lasts longer than a primary spike( pleasure derived from pure hedonism/ eating chocolate/ sex/ romantic love) So the question is, how can I make my sex/pleasure experiences into something that takes effort? And by effort, I don't mean the effort to avoid a broken heart or to avoid shame tactics. Not sure what for. the effort would take.

Any advice? Any brain chemistry hackers out there?

Save this hedonist. ( mods, please know this is all about sex)
