My bf is into ball play

I wanna start this off by saying I have absolutely no issues with this. There's nothing weird or strange about it to me I've just never been with somebody who likes it! I've been with a lot of people and my bf has only ever been with me so he doesn't exactly know where to go from here communication-wise. He asked me once during a HJ if I would touch his balls and ofc I agreed and he loved it. Last night I gave him oral and decided to put them in my mouth and he loved that even more! I really like making him feel good and just want more tips on things I can do that would do that for him 🙂
