boyfriend is worried he won't be able to make me cum

I feel stupid but honestly I can tell he's really down about this and so am I. I'm 18 and a virgin and my boyfriend is 20. We talk a lot about my first time, and almost everytime we talk about sex it gets all serious and one of us ends up being upset. I have bad anxiety and naturally of course I'm nervous as hell about my first time and he wanted to know why so I told him I feel like I won't be good enough and he told me we'd work through it. Then he said he was worried about not "performing" well and nervous that he might go soft so I told him it's okay because I'm almost in the same boat, I don't know if I'll be able to orgasm. I've been masturbating and experimenting for years by myself and I really only ever get off from clitoral stimulation. Fingering does absolutely nothing for me, but a toy is somewhat better.
