Is it normal for sexuality to fluctuate? o^o;

I’ve been wondering this for a while and was curious if any of you knew a word for it or felt this way too. //casual TMI mention just because I’ll be vaguely mentioning sex drive? It’s not detailed or actual TMI.///

I’ve noticed that I fluctuate through two sorts of settings; very high libido and a literal absence of libido. I mean, I can control myself when I do have a sex drive, but it’s a pronounced presence. However, I suddenly switch to long periods of time where I’m sex repulsed? I’m in one of those right now, where I’ve been relatively sex-repulsed for about a month now. These shifts can last days, weeks, or months at a time. My romantic orientation and level of desire for romantic contact is consistent, but it seems my sexual orientation, while consistent in who I’m attracted to, exists like a light switch that I have no control over and has no rhyme nor reason.

What are this?
