Need advice😝

Alright ladies of glow I need some advice😂 so I'm in a FWB relationship.  Yesterday we had really hard sex. Well I was taking a shower earlier and noticed that he left some bruises😉 I personally don't mind them but anyway I was wondering if you were in this position would you tell the guy at all and if you did would you say it in a funny way or send a pic and say something? I wanna let him know he did a good job but I have no clue what to say😒😂
