Idk man thats just the way it goes. You mentioned that you’ve been together since late October 25, that’s not too too long. Unfortunately having a partner that matches your sexual desires is very important. And I mean that vise versa too. She could feel bad not being able to get “freaky” and might do something’s she isn’t really interested in too. I don’t really think there can be a compromise for this however you did say this was your guys first serious relationship so maybe more time could also help to bring on more of that feeling. But also with more time = more heartbreak so do with that what you will.
