A common myth people ask is, “Does sex make you gain weight?” and the short answer is: No, not directly. Sex alone won’t magically grow your ass or thighs. However, regular sexual activity can influence your body in subtle ways. Here’s how:

Hormonal shifts during regular sex might boost your appetite or change fat distribution slightly, especially if you’re more relaxed, sleeping better, or eating more afterward.

Physical activity during sex can tone muscles, especially in your core and lower body, but this doesn’t equate to major weight or size gain.

As for swallowing cum, it has around 5–7 calories per ejaculation, nowhere near enough to make you gain weight. That’s like a sip of water.

In summary, sex is not a weight gain strategy, and semen won’t fatten you up. If your curves are growing, it’s more likely from lifestyle, diet, hormones, or genetics not the bedroom.
