Let’s talk about penis sensitivity. Some men wish they could feel more—like every little touch, lick, or tease is an electric jolt of pleasure. Others? They wish they could feel less, because finishing too soon can be frustrating (for both of you). And then, of course, there’s us women—who, if we’re being honest, generally wish he could last just a little bit longer.
If you’re in a female-led relationship, male chastity dynamic, or just love experimenting in the bedroom, understanding how to manipulate sensitivity is an absolute game-changer. And one of the biggest keys to this? Substance P.
Substance P is a neuropeptide (a fancy way of saying a small protein that affects the nervous system). It plays a major role in pain, pleasure, and sexual sensitivity by controlling how nerves communicate. My neurobiology classes are paying off with today's blog. When you have more Substance P, nerve endings become hypersensitive, making touch feel more intense. When you have less Substance P, nerve endings are numbed and less responsive, meaning a man can last much longer before orgasm. I'm sure others could do a much better job of describing what Substance P is but for the purposes of this blog I'll leave it at that.
Think of it as a pleasure dial—more Substance P = more sensitivity, less Substance P = more control. And guess what? Controlling him can be fun.
Capsaicin is the active compound in chili peppers that makes spicy food burn. It directly interacts with the vanilloid receptors in nerve endings, which control heat, pain, and (most importantly) sensitivity. When applied topically in small amounts, capsaicin temporarily blocks Substance P, creating an effect that’s like turning up the volume on sensation. When taken internally (like in food or supplements), capsaicin actually depletes Substance P over time, leading to a long-term reduction in sensitivity.
So depending on how you use it, capsaicin can either boost his penis sensitivity for a night of fun, or train him to last longer over time.…
