I have a problem... 😬

Okay so basically I’ve been in a relationship with my boyfriend for six months he’s so so perfect, and I’m genuinely in love with him, he’s an amazing kisser, really funny and kind with a sensitive side and probably the most amazing boyfriend ever. But the only problem is that I can’t get turned on down there and I don’t know why. when we first started dating it was definitely there but now it barely ever happens and even then it’s really random and only lasts for a couple of seconds, I don’t understand why I can’t get it going, hes one of the most attractive people I’ve ever seen and he does everything I like and is very skilled at the things .. 😏 but for some reason my vagina is working against me here and it’s really really annoying me, is something wrong with me ? Any advice ladies ? X
