Has anyone ever used ben wa balls or a yoni egg?

So my partner and I usually have sex like once a month or once every other month. It's infrequent basically cos he has thing about abstinence. Anyway, he took a job out of state Monday through Friday. By the time he comes home Friday, he's horny. We've been having sex a lot more often. Last Saturday we had sex and he joked that I must be cheating on him cos I'm not as tight as I usually am.

Background: I'm a rape trauma survivor so it takes me a while to warm up. And by a while I mean in the middle of penetrative sex. I get wet but I don't get relaxed and turned on until he's blowing my back out basically. And he knows about the rape trauma piece. He just doesn't know about how long it takes for me to get fully relaxed.

I have ben wa balls and I just wanted to know have other people used them to increase muscle control and "feel" tighter. Do you think yoni eggs work better? Just want some advice.

And, if anyone is wondering, I did chew him out for his comment. I also joked that that must've been why he lasted for more than 15 minutes. He didn't hurt my feelings. I'm just more self conscious about it now. 😓
