I would say a strong desire and interest is normal. Actually doing it --- reaching out and touching people that have not asked is not. Hope life turns out for you to be such that you can have a healthy sex life with a regular partner (as in a wife). good luck
Sounds like you have some raging hormones. Obviously, touching women who have not invited you to do so is a no no. Do NOT be tempted in that way as you will get in trouble. And if you are hounding for sex all the time around the women you know . . . they will possibly be uninterested in you because they know it is much more about the sex than them.
Ever dated or been in a relationship? How old are you?
