This is an interesting one.
Having had a number of short and long term relationships, spoken to lots of people about relationships etc, I have reached the conclusion that for some people sexual attraction genuinely is largely about looks, or at least, is dependant on looks (there may be other factors too). For others it’s just not that important, myself included. I can find all kinds of men and women sexually attractive, regardless of how they look. The same seems to be true for my current partner - he’s objectively pretty stunning, and has had partners who are much more conventionally attractive than I am - yet I totally believe he finds me very sexually attractive - his words and deeds demonstrate this, and I never ever feel insecure about that aspect.
My most recent ex on the other hand did not find me sexually attractive - he told me so (which I think is pretty fucking rude, personally, considering the fact he still expected me to have sex with him). He was very concerned about looks it seemed - and while I’m not bad looking I don’t think, I’m no picture-perfect pin-up….(nor was he either - in fact funnily enough most of my friends and family told me afterwards they were astonished I was with him to be honest - he was much older than me and really looked a bit weird. I did fancy him at the time tho…) . I’m delighted (in retrospect) that we broke up, as to me life is far too short to spend it mithering about having perfect hair, make-up, perfect figure etc, all my life, just to please a partner…..
So if I were you I’d ditch this one and try and find someone who finds you attractive because of who you are, not what you look like. There are plenty of us out there, male and female, as this thread shows. Only some people find looks such an important part of fancying someone……
