I’ve lost my sex drive.. what do I do?

Hi guys. I’m 20 years old and have been with my partner for 5 and a half years and I love him to bits.

Recently though I went away for 7 weeks and I’ve come back and have totally lost my sex drive. I’m never horny and never turned on by the things he used to do to turn me on. We’ve had sex 3 times in 2 months. Because I just don’t want it. My body doesn’t want it but my head and heart do if that makes sense.

What should I do?

P.S. I am totally attracted to him too so that doesn’t seem to be the issue
