He’s 16 and I’m 17 and have been together for about 8 months. He got a big pack of condoms like 20+ and I know this sounds insecure but I do keep count. For the past week we’ve been having sex in the morning and at night, so 8 were used. But there’s an extra one that’s missing. I asked him about it and he said we used it. Finally later when I asked again he said he gave it to his friend who needed one as his stash was old. Idk even what to think. His search history on FB is filled with girls and he’ll look the same girl up 7 times back to back. He does this teen youth program and he looks all the girls up from that. I haven’t said anything to him but it does hurt and now there’s a condom missing which he originally lied about
