Hard time getting hard

So my man for some reason has a hard time getting hard with me he says he thinks I’m attractive etc etc but I’ve never been with a man that doesn’t “most of the time” get hard the second I start to do sexual stuff or idk just randomly cause he thinks I’m hot etc it’s a bit of a turn off to have to work for 5-10 minutes just to get him hard every single time and it’s frustrating I do get every one’s body’s are different etc etc but this is an every single time thing not every once in a while I’m not sure why I’ve tried to ask him why it’s hard for him to get hard around me but how are you supposed to ask that question without sounding like a total B idk wtf to do honestly but it hurts my feelings ig does he not actually find me attractive he’s 22 and im 20
