Is it weird that I wrestle with my boyfriend..?

i was at my boyfriends friends house (roxanne) and she was having a house party and we stayed late to help her clean, plus we were spending the night. he does martial arts and hes a black belt so he spars a lot and i told him i could beat him and pin him down haha. so he's like 6'0, 160 lbs and all y muscle and im like 5'6, 107 lbs so we started wrestling and it was pretty rough. eventually i was sitting on him and had pinned his arms to the floor and she walks in like "woah are you two wrestling? most couples cuddle but not you two..". haha so i was just guessing if it was out of the ordinary to throw eachother around and stuff..
