How can I incorporate kegels into sex?

My bf and I were having sex and sometimes when he stops while he’s still in me I’ll do a kegel or two just for shits and giggles to see if he notices. He does and usually he’ll joke and tell me to stop trying to push him out or stop squeezing his dick. He never verbally said he liked it but he also never said he didn’t, I just figured it did nothing for him since he never really asked me to do them or pursued that aspect more.

But this time we were having sex and I did a kegel and he asked me continue. He wanted me to do them when he was thrusting but I couldn’t keep up with that and with him moving in and out it didn’t feel like I was actually doing anything. And I didn’t really know when to squeeze and relax. I think he was into the kegels though bc I asked if he could even feel it and he said yeah, he said it felt tight. And it sounded like he enjoyed it?? Or it at least sounded like it felt good for him. So how could I incorporate that into sex without it seeming random and weird?

(Ofc I’m going to talk to him and ask him if he liked it or if it really did anything for him and if that’s something he’d like me to do sometimes)
