first time

so me and my boyfriend recently started having sex, and he is the only person I have ever done it with. but everytime we try to have sex nothing feels good for me. either I feel nothing at all or it just hurts. we both get frustrated, and eventually give up. he's only ever had sex with 2 people, but he says he never had this issue with them. when I masturbate with a vibrator I can always get myself off, but it's never from vaginal penetration, it's always from clit stimulation. even when he gives me head it never feels good. helppppppp 😭
