10/10 goob but very bad humour

I wanna date this 10/10 goob but they say things like pee pee poo poo or make jokes about drinking and commiting crimes. When I tell them I don't like those jokes, they say I'm overreacting. Am I overreacting and will their humour change as they get older and mature? I really hope it does 🙏 They are 15 and have autism (may be the cause of the humour but idk) (I don't have anything against mental thingies btw :3 I probably habe autism too)
