I think it depends on the individual, and everyone has a slut phase. For example, when I was a teenager/young adult I had little respect for other peoples feelings, and never really considered the consequences of my actions, that what I did could hurt someone else. So I dated & fucked around a lot, then got to a point where the thought of relationships were actually disgusting me, bc I didn't want to hurt anyone, or get hurt again.... So I stayed single for a few years, and really just worked on myself, now, I'm older & don't seek attention, or attribute my self worth by needing another person to make me feel better. I'm in a good place & have found a great partner I've been with for 3 years, and honestly don't even think about other guys or ever wanting anyone except him.
