Loss of libido/sex drive

Hey ladies I have a pretty dire question or rather statement I need advice on... I am 21 and feeling a drastic loss in my sex drive/libido. I feel it's super strange that I no longer get horny or wet considering the fact a few months ago I could get wet on command and get horny whenever I felt. I had absolutely no problem with it, infact i considered myself a nymphomaniac. Now this loss of sex drive is really concerning considering I'm only 21 and my boyfriend is asking for sex like 2 times a day. I don't want to not give it to him but lm just not feeling it and now he thinks it's because I don't find him attractive anymore. Also may I add In also quitting smoking weed, I'm about 2 weeks in and am considering it's because of that. Please help!
