What can I do

When my boyfriend and I are getting frisky and having some fun, sometimes he’ll tell me to stop or he’ll just get soft and says that he feels like he has to pee all of a sudden. More recently he pees before we start anything and is usually fine for the rest of the time, but there have been times when it doesn’t matter, he gets that feeling and we have to stop. Mostly it seems to happen if I’m using my hand on him or sometimes if I’m blowing him. Sometimes it gets annoying having to stop or I feel like maybe I’m pleasing him enough (has nothing to do with gender roles. I get more pleasure out of pleasing him than having him try just to please me. So it’s mutually beneficial). Is there anything that might be causing this? He was a virgin before me and has no experience besides me. Is there anything I can do to help with this? I don’t know if I can do anything about it or if I should just live with it.
