one song!!! 😩😭

So my bf and I have  been playing music lately while having sex , sometimes we last a while doing it but I think and to be honest lately he's been lasting less than a song! πŸ€”πŸ˜©πŸ˜­πŸ˜… 
Last couple of times! And it used to be annoying but now it's frustrating! Lol cause I want to finish too, you know? 
But I never say anything or get mad so he doesn't feel bad :/ he's really good, but he's faster than me and when he's done I'm barely at the "ohh yea it feels good, don't stop" part lol 
Is this because it feels too good πŸ˜ŽπŸ’…πŸΌ
Or age? (He recently turned 30)
What is this??? 😩😩😩
