sudden increase in sex drive

I’m a 22 year old female and recently I’ve had a severe increase in libido. Like I actually feel like I’m going crazy. I am engaged and have a 4 month old baby so I don’t know if it’s because of my hormones from having a baby or not but Oh my god! It’s like every guy I see either on tv or in real life I want to have sex with them and even sometimes girls. I have sex dreams all the time and I feel like I’m losing control. My fiancé doesn’t have a high sex drive at all and it frustrates me. But like we can just have sex and I want to do it again right away. Does anyone else feel this way?
