Sex drive makes me feel so bad about myself😞

This last week my sex drive has been crazy high. I just want to have sex 24/7. My SO cant keep up with me and I feel bad for asking multiple times a day. I know he doesn't feel this way about me but I feel like he thinks I'm acting like a slut because I'm wanting to try new things that we have never done. If he tells me no about sex I just go into the bathroom and do it myself. I feel like its getting out of hand. If I dont get pleasured when I want then alls I can think about is when I can have sex next. I've never in my life have been like this is this normal to feel in 3rd trimester? I just feel so nasty about myself.
