Not even something you should rush into. Talking about serious relationships here, not high school drama. I got my first girlfriend after I'd just turned 18, she was nearly 21. Came to love her to bits and we had amazing chemistry, but I wasn't prepared for the mental stresses of having a girlfriend; I acted like I was still single even though I wasn't. And I didn't know how to the deal with the inevitable arguments and troubles that come with any relationship. Honestly bro just date and -blam!- around until you're in your 20s at least. I'm 19 now, been single nearly 8 months (phuck that's gone by fast) and have no desire to be in another relationship for a good while now.
