Is being frisky often bad?

So it’s been a month since I had sex with my fwb but lately I’ve been wanting to sleep with him more like to the point where anytime we would hang out I want to rip his pants off and blissfully live on him. The last time we had sex I was still horny and it caught him by surprise that I’ve been like this. I finished my period few days ago and I haven’t ovulated yet so I normally wouldn’t be like this. I’m afraid that there is something wrong with me since I’ve never experienced this before. Has anyone been like this? I’m just hoping it’s nothing bad.
