He only wants to finish on my face

I don’t know what’s going on with my bf, but he only wants to “finish” on my face when we have sex.

I don’t mind it sometimes but I don’t want it every single time. We are in our late 20s and live together and have been together for 4 years.

I’ve told him so many times that I don’t like that and to just “finish” inside me. I’m on birth control. He use to all the time.

When we have sex I ask him to finish inside me and he says “ok” but then when he actually does, he pulls out and does it on my face.

Am I with an immature teenage boy ??? Because it’s awful that he’s not listening to me. It makes me not turned on anymore.

Any advice ??
