HELP! Losing interest in sex 😨

My sex drive has dropped exponentially over the past year or so. We’ve been married for more than five years and he’s a GREAT husband; compassionate, hardworking, fun, all the good things. But my interest in sex is just not there.

-I can’t climax via penetration. It’s so frustrating because he’s the sort of guy that’s willing to try/do anything to make sure that I cum. So I’ve faked it.

-I add clitoral stimulation but that doesn’t seem to work while I’m with him, though it works during masturbation.

-He lasts forever, which I know is supposed to be a good thing, but then I just get sore and tired. It’s like I lose arousal during sex and I’m just...there?

-Porn doesn’t help because I don’t enjoy porn. (I know I’m a minority on this app lol.) I’m like...but that’s not me 😂

I don’t want him to feel like I’m losing interest in him because I adore him! And we still have sex because I know he still likes it and he fucking deserves it! Lol. All the sex! But I wanna love it to 😭😭😭

Help! Any suggestions?
