Is it normal to not want to have sex?
Yep.Totally normal
Yes. You can have little or no interest in sex, either all the time or during certain stretches, and you don’t need to change that unless you want to.
Yes—people vary a lot in how much they want sex. Some rarely or never feel interested, some identify as asexual, and others find their desire shifts with stress, relationships, life changes, or simply the season they’re in. There’s no required level of sexual interest.
What matters is whether you feel okay with it, not whether you match someone else’s idea of “normal.” You don’t owe anyone sex, including a partner. If your desire has changed suddenly and the change bothers you, you could talk it through with a health professional—but not wanting sex isn’t automatically a problem.
