sex drive completely gone

Im starting to get worried that there is something really wrong with me. I have always had an insane sex drive to the point my ex boyfriend and I would have sex three times a day and with other people past that I would as well. Then all of a sudden for the last 5 months I had genuinely not had an ounce of interest for sex. I am only 21 and have no interest in sex at all. I’ve been drugged before and had many guys do awful things to me so I am wondering if they have destroyed that for me or my brain is just simply done having sex. The main issue here is that I will hang out with a guy that I like and they get frustrated that I cant meet the expectation of having sex and they move on, which in my opinion is fair but so hard to deal with for me. I say no to it every time when I used to be down for it where ever and when ever. does anyone know what this could be or how to fix it??
