To make your nipples hard, you need to sexually stimulate yourself. Massage your boobs, rub them, squeeze them, etc. Also, flick, lick, and touch your nipples as much as possible. Your nipples will get hard once you're horny and sexually stimulated.
when they are horny
Flick them, get cold like in a cold pool or super hot like in a shower. Or when u are horny they'll get hard (if you are a girl)
no, if u r cold your nipples tend to get hard. Women will most always get hard nipples when aroused and most men wont, but some do. if u r Mae and get hard nipples when aroused it doesnt mean theres anything wrong it just happens.
Nipples can become erect or hard due to arousal and the release of oxytocin, a hormone associated with sexual pleasure. Increased blood flow to the area can also contribute to nipple sensitivity and firmness during sexual activity.
