Is it normal to now want to have sex anymore???

I’ve been with my boyfriend for almost 3 years now, we’ve been living together for about 2.5 years. In the beginning our sex life was great. Then it got to the point where I felt like a horn-dog because I was always horny and he never initiated sex. We’ve had multiple conversations about this and he got a little better about initiating sex. Well now I’ve noticed over the past like month and a half that I just don’t want to have sex with him. Like I’ve ALWAYS been the type to be down for sex especially like multiple times a day. We’ve probably had sex maybe 5 times over the past month and a half. Also I’ve noticed that when we do have sex it’s hard for me to get wet, which has never been a problem before. I just don’t know if this is normal or not. Lol. Please help.

Let me add I’m completely 100% in love with my boyfriend. I know he is going to be the man that marry and have kids with. It’s not that I don’t want to be with him anymore. I just don’t want sex with him right now.
