my gf (22F) and me (21M) have decided recently to open our relationship on her side for sexual encounters only as it's not something too appealing to me but it's something she really needed so we are basically monogamish as of now and of course we both agreed to it and have clear boundaries set up. Now I've never been too into this of having my partner have sex with someone else although when i think about it the idea can be quite arousing hence why I dont have a problem at all when we opened the relationship. But now she had her first sexual encounter with a friend of hers and i can't help but feel a little jealous about it, they are currently in a hotel and she won't be coming back home to me til Wednesday and of course I've communicated this to the and her answer made me feel at ease which was "it's okay, honestly I'd be sad if you weren't even at least a little bit jealous, this just shows you care about me and how important i am to you" but well... I'm still feeling it a little bit, although i trust her and it already happened and she already reassured me and I know that jealously is a valid emotion im allowed to feel, is there a way to like stop thinking about it or work through it that some of you guys might know or might have worked for you? currently im just trying to think about what we'll do (in the sexual sense lol) when she gets back but idk haha i really could use a bit of help on this one as we are both very new:) thanks for reading and for any help in advance <3!
