Nonexistent Sex Drive

Im honestly shook because my sex drive seems like it doesn’t exist anymore??

I’m 20 and have ALWAYS had an extremely high sex drive but the last two-three months I haven’t had one at all. I feel really bad for my S/O because I know he wants sex and when we do have sex it’s such a hassle for me. I’m never “in the mood” and 99% of the time when he wants to I just want his dick automatically hard so we can get it done and over with.

I love him endlessly so I know it’s not because I’m not interested in him. I’ve always struggled with body-image issues but it’s never stopped me from wanting to get jiggy. I just seriously need some advice or maybe supplements to take. Any help would be extremely appropriated!
