Not like me at all!!

Sooo long story short I went off my birth control the week of Christmas, had a period in January and March. No period in February or April and so far nothing for May. We aren’t actively TTC but aren’t using anything to prevent it. If we got pregnant we would be thrilled. Our plan is to start actively trying in November if we aren’t pregnant by then. I also took a pregnancy test this week that was negative. Anyway to my real comment...My sex drive is all of a sudden off the charts high. I had been on birth control since I was 14 and didn’t lose my virginity until 18 and I am now 25. I have never been this horny in my life. My fiancé has a low sex drive so we usually have sex about once a week for me and I’m usually satisfied with that. Not right now though! For about 2 weeks I’ve been horny non stop. I’m masturbating in the morning and at night when normally I masturbate maybe 1-2 times a week. On the days we do have sex I don’t want to stop but he tires out. I just masturbated like an hour ago and am thinking about sex already! It’s consuming my thoughts. Every time I listen to songs, watch movies, read books all I can think about is the sex scenes and comments. What is up?! What should I do?? I’m too embarrassed to tell my fiancé how bad I am craving it because I already want it more than him and don’t want to make him feel pressured to do it more if he doesn’t want to. I just don’t know how to satisfy myself! Help!!
