Partner has a difficult time dealing with my asexuality

Hi, I'm 26 and asexual and I currently have a partner of almost 2 years now. It took me a while to accept the reality of my asexuality, and I faced so many failed relationships that culminated to a very toxic and dangerous relationship before I was able to realize that yes, I am asexual, and yes, it's okay to be asexual. I've long accepted that I am asexual, sex-averse, but not aromantic and I've always tried to warn any potential partners I have since I know it's not the "norm".

But 2 years ago, I met someone and after informing them and everything, somehow still accepted me and wanted to be my partner. Honestly, at that point I was perfectly content and at peace with the thought of being single forever, since I know it won't be an easy task to deal with me and my baggage. I was surprised by the acceptance and we became officially romantically involved.

However, problems regarding our sex life began to arise. My partner began wanting for a more active sex life, and would often try to coax me into having sex. This would either lead to me just folding and just wanting it to be over, or it'll lead to a big argument or self-pity session from my partner.

Now, my partner is trying to convince me to get therapy to "cure" my dislike of sex, and when I remind them that I informed and warned them of my sex-averse tendencies, they always answer that they didn't think it would be that bad. I don't even mind if my partner finds someone else to do the deed, that discussion isn't off the table, but my partner always declines.

I just feel so heartbroken because what was once something that I've wholeheartedly accepted, something that I once thought was broken was apparently not, is now something I have to "cure" and "change". I have such a long laundry list of mental health issues that I was so happy when I could remove one thing from that list and I could hate myself a little less. But now it's like I have to put it back on the list and seek therapy for that just so I can satisfy my partner's libido?
