Help please

Some advice please

Hi, I’m a M21 and i’m with my gf who’s a F23 we’ve been together for about 3 years now and i love her dearly, so much so that we’ve moved in together recently.

I’m kind of just posting here to grab a bit of advice, we used to be very sexually active especially in our first year she was at uni i’d visit every weekend and it would be nonstop for hours on those days and when she finally finished uni she came to live with me at my parents house where it obviously cut down drastically, maybe once a week i even remember one time where nothing happened for 2 months. I thought with us now moving to our own place it wouldn’t make a change as she can feel more comfortable as no one is in the house but it seems like everything is the same. I’ve talked to her about it but she never gives me much back and i’d just like some opinions.
