Confused potato

Honestly I've just been feeling like something was wrong with me for so long. Manly because like, I don't have the desire for sex. It makes relationships really hard. At first I do it because I feel like I have to but it just feels like a chore. I never understood it. I've had a couple different partners since I first had sex with someone at the age of 17, I am now 26. Even then it felt different, like a chore. I just thought maybe I haven't found the right person though I have been with my current partner for over 2 years now and I love him dearly and we have fun together like most couples and I have like romantic feelings for him but when it comes to sexual feelings it's like there's just nothing there. I didn't realise like there was a name for it. I have been reading up on it for a while now and have asked friends that feel the same way. I know there's a large scale when it comes to sexuality but it's so daunting. I only spoke with my mom about it on the weekend just gone and have just confided in my best friend about it as well. I'm too scared to mention to my partner in fear of his reaction.
