I need help

So yesterday my boyfriend & i had sex together for the first time... i was a virgin, him no. He wasn’t fully hard although i wanted him to be. He told me in order for him to get fully hard i had to suck his dick but i was too nervous (yes i was too nervous to do that than lose my virginity it’s weird) but i feel there’s other ways to get him full hard. I just think it’s ME that maybe IM the one who can’t like maybe he doesn’t get turned on by me or doesn’t find me sexually appealing or something and those thoughts are driving me crazy because helloo i want to be able to get my boyfriend hard ! I know every guy is different Bc my sisters boyfriend gets hard with them just making out but still. Then also, he took almost 30 mins to cum & idk if that’s bad or good.
