CANT MAKE MY BF UNDERSRAND HELP!

Okay so as y’all know only a certain amount of women can fun from dick alone every time . I am not one of these women. Sometimes I will fake an orgasm because he will force himself to not cum until I do. I feel horrible afterwards so I end up telling him the truth. I don’t want to lie to him in the first place but I don’t want him to have to think about basketball while we are having sex. But after I tell him he will feel really insecure thinking he can’t satisfy me . I keep trying to tell him it’s just the females body and “take it up with God” but he still thinks it’s him. How do I get it in his head that it’s just how I am. Or do I have to take orgasms and just not tell him I didn’t cum?
