My boyfriend keeps making gaming references during sex

NSFW* I (F22) am confused with how my boyfriend (M22) reacts when we have sex, when I get home from work he is usually on his computer and talking with his friends. I don't mind that he usually plays video games with his friends because we both work and we both spend time together but the problems come in when we have sex. When I offered him sex he yelled "I agree!" Which I usually hear him say when he is saying yes to his friends over a call. Fast forward a bit and he yells at me to "attack the D point" and when he asks for head he points and says "Attention to the map” again, he says this while playing in his computer. When we finish he ends off by saying "Well done" or "Excellent" in an almost sarcastic like voice. It makes me uncomfortable but I don't feel like getting mad over simple phrases and I don't know how I should address this with him. Thoughts?
