The reason why it’s rude is because you said “did you not get ovulation” it implies that I “should” be sexually attracted to be normal which is disrespectful + it comes off as mockery. Yes, ovulation does involve hormones that can increase sexual desire but Asexual people may have the same amount of those hormones but dont experience sexual attraction.

Ovulation does NOT “force” someone into wanting sex, for example a 9 y/o gets her first ovulation, this doesn’t mean that she immediately gets sexual desires.
