One guy, two girls? How was it?

I want to have one with my guy. He joked about it for some time and I would always brush it off. But the other day I seriously asked him would he give me one and he said no 😔. That he doesn’t want anyone being able to say they had sex with me and him 🤨 this whole time I thought he was serious about it and not sure if he’s just being stingy. What’s a girl to do 😫
