I’m frustrated

I’ve talked to my husband several times about initiating sex and I feel like I keep having this conversation. I’m tired of arguing about it and I’m tired of asking him for it. I’m hurt when I get turned down even tho I know he’s tired and stressed I get it, so am I. Idk what todo I just wanna stop asking & masturbate... but I know that won’t help anything...idk what todo 😟🤦🏾‍♀️
