I like the point that you can enjoy your time with a variety of men, but if you are seeking to settle down those men would be less than ideal.
I think #1 applied to an old boyfriend. I was madly in love with this guy in my twenties and he professed his love no end but he never committed to anything and I stayed way way way too long. 5 years is a colossal waste of time.
I don't know that 'every woman needs' to date these guys. One is probably enough. 5? Oi Vey.
