Sex drive question!

Hey y’all! So I was just wondering if anybody else was maybe dealing with the same stuff here.

So my drive is very slowly starting to return in the second trimester, I’m now 16w3d. However, I absolutely do not want to have sex with my boyfriend. Hugging him is about as much as he’s gotten in at least a month. 😅 But whenever my needs do surface, I only want to get myself off. My orgasms are incredible and are lasting longer than they ever have. I just. Cannot. Bring myself to have actual sex. I love my boyfriend dearly and have always been very attracted to him. That hasn’t changed. I don’t know why I’d rather take care of myself, and has anyone else dealt with this??
