Help! Is he cheating?

My boyfriend and I live 90miles apart, we see each other on the weekends and it’s hard to talk every night throughout the week. We’ve recently discussed moving in together and I plan to sell my house and find a new job.

I got to his house this weekend before he was home. I tossed a few things in the garbage and then realized I needed something out. When I went to look for it, I found a condom wrapper. We don’t use them anymore so I know it wasn’t from us. My crazy immediately came out, before I knew, it I sent him a photo asking why there was a condom wrapper in his trash. His reason was he jerked off into one the other morning. Is this a thing? Should I be worried? He hasn’t shown any other signs of cheating and I doubt he brought someone to his house with all my personal belongings throughout the house.

I just need reassurance.
