sex is a learning experience right?

So my boyfriend and I had sex for the first time this weekend. I haven't had sex in almost 7 years (I'm 32) and my boyfriend is 29 and was a virgin. He couldn't really keep it up and I feel bad cause he fingered me and I came 3 times and he didn't get to come. He told me that he jacked off all week. Does that have something to do with him not being able to keep it up? Will his body be able to learn to keep it up soon? What should I do to help him keep it up?
