Asking for advice?

So me and my partner have been together little over a year. He’s known from the start that I’m friends (PLATONICALLY) with guys for the most part (I only have 2 girl friends). He didn’t have any problems with it. I use a site called fetlife often and he started having problems with me making friends on there end of last year, his reasoning was because they’d seen my raunchy photos. So I understood that and stopped meeting people from fetlife. I’ve recently reconnected with an old friend from highschool and we were planning to hang out this weekend, but my boyfriend has a problem with it and won’t tell me why. When I try asking him why he shuts down the conversation and changes the subject. It’s really annoying me. He’s had no problems with who I’m friends with up until end of last year, and now it feels like I’m not allowed to make new friends or reconnect with old ones. Guys, what are your thoughts? Keep in mind my boyfriend has a lot of female friends so I don’t think it’s a case of he’s against me having guy friends.
