I actually think you are pretty promiscuous. I mean 15 partners before 25 and only 4 of them in semi serious relationships. That's a few partners and a lot of hook up. Also how is it around 15, is it 15 or more or less than 15, do you even know the exact number? As a guy that number would make me seriously second guess being in a relationship with you personally. I think you like sex and haven't been in a relationship with anyone you actually cared about. Sorry to say but it does sound like your ex may have been right. I mean if you lose interest after sex it makes me wonder if you actually had feeling with any of those guys before you even slept with them.

this question sounds a bit troll-ish, as 15 sexual partners for someone who's 21 years old screams either 'fake' or 'dysfunctional'. however you look at it, you seem to be slightly in denial, as that's exactly what 'promiscuous' behaviour looks like. maybe you're using sex as a way to feel empowered and validated, maybe you think that's what men do to normally assert their own individuality.. but you know what? even a 21 y. o. guy who slept with 15 people is not exactly a mentally 'healthy' individual. he'd be someone who needs constant validation from sexual partners, without even spending any amount of time to know them on a personal, human level. thus 'using' them to fill some personal void. all I could say is that I'd strongly recommend therapy.
