For women, no. (Men: see below.) The whole experience changes the more often you masturbate and have sex because you start to learn different things about how your body works AND you also start to RECOGNIZE the feelings that are building up in you.
When you first start masturbating, all the feelings and sensations are so new and overwhelming, you have no idea what to do with them and how to process it. Later on, you know what to expect, the newness isn’t there anymore, HOWEVER, this does not mean less sensitivity.
You actually experience more powerful orgasms as you experiment sexually because you figure out how to maximize your pleasure. It’s just a different feeling than the first few times you had an orgasm because back then it was NEW, not stronger, just NEW. Women don’t lose sensitivity, we gain experience.
MEN! Unfortunately, the same cannot be said for you! Yes, you do lose sensitivity when you masturbate frequently – especially when you jack off roughly. If you grip yourself too hard and you’re too “FULL THROTTLE!” when you beat off, you lose sensitivity in your dick and it makes it more difficult for you to cum when actually having sex. What good is a soft, warm pussy when your hand has had your dick in a vice grip every other day of the week? You’re fucking yourself over and not in a good way!
Guys, take the foot off the pedal when jacking off. Do it less frequently and loosen your damn grip. If all you want is your hand to share your nights with, then by all means, ignore what I’m trying to tell you. 😉
