Am I being too paranoid/controlling in my relationship?

r/

This is my first time posting on reddit but I honestly just want different inputs and thoughts on what I should do. So I (22f) and my boyfriend (23m) have been together for just under a year. I have dealt with insecurities when it comes to relationships and can never tell if my feelings are valid or not. My boyfriend had seen this girl for a couple of years without ever really dating and at one point she got a boyfriend but they still kept seeing eachother. Once we got together he said he would block her on everything but I just found out he still has her on one platform just incase she needs anything and just wants to be able to see how she’s doing (I want to add although we were not official yet he had told me she had sent him nudes while he was in my bed next to me, I know we hadn’t discussion exclusivity yet but his sexual world is so much different from mind I still find that crazy) I don’t want to be seen as controlling but It makes me uncomfortable and I don’t know how to go about it. Another issue that has popped up was that since we started dating women have always popped up on his phone with me having no knowledge to who they are. I finally asked him about it and he said that he keeps in touch with these women friends because of “streaks” and he uses that as a reason to talk to them every day sometimes multiple times a day. Which makes me pretty uncomfortable since he doesn’t hangout with them i guess he’s never had a reason to tell me about them but finding out he’s contacting girls frequently without me having any clue and not knowing who they are just threw me off guard. I don’t use snapchat but I have heard what’s its used for and know the messages delete. for background- I really try and keep and open mind but a lot of his family members have cheated and some of his friends as well, and what really bugs me is that he would knowingly keep seeing the one chick while knowing she had a boyfriend.Should I be worried are any of these red flags or am I just being controlling?

TLDR: Is me asking him to limit contact or cut ties being to controlling
