My boyfriend and I only have sex about 3 times a month.

He’s 24 I’m 23. I feel like while 3 times a month may be enough for some people, I just have a higher sex drive… it’s been 3 years of me telling him over and over again and nothing has changed. So idk I’m started to like hate my sex drive and for the longest time I thought it was me but I’m just getting so tired of getting rejected because I cannot help but take it personally, which I know is partially because I’m just insecure and sex reassures me. Anyways it’s really affecting my mental health. Is it normal to have so little sex or do I just have a high sex drive ??
