Sex w/ Boyfriend for the First Time

So tonight I had sex with my boyfriend for the first time. I was insanely excited for this experience because he’s 10 years older than me so I thought he’d have a lot of experience. Well, the sex was less than stellar and I don’t know how to tell him 😨 I didn’t come and he didn’t seem to care that I didn’t come. He said “oh well maybe not tonight.” ?! Uhhh what?! He didn’t even l foreplay with me 😭😭😭 what do I do?! He claims he has a huge sexual appetite but he doesn’t act like that in the bedroom....help!
