It's your kid, but I'd temper the advice with this:
1)There's no such thing as the perfect mate. Looking for perfection will make you dissatisfied with everyone you date.
2) A lot of what makes a relationship work or fail is how you treat each other, not who you're with.
3) "Playing the field" too much desensitizes you. Your memories with your mate are mingled and confused with memories of lots of others. You keep doing mental comparisons. You have fewer unique experiences together. It just seems less special. So look around, sure - but don't make a sport of it. Lasting love is way more satisfying than a lifetime of flings.
