Why am I horny all the time ??

lala

I get really horny talking with this guy I’m seeing , sometimes after waking up, or just having my legs crossed . I have nexplonon in my arm could that be the reason? I want to control my sex drive because I live with my parents and I don’t want to be pinned up in my room because I don’t want to be walking around horny or with horny thoughts. I want purity
