Well that comes with being a woman. You have the luxury of picking and choosing.
I do like to check my Tinder, OKC, and PoF just to see if anyone ran across me and sent a message, and I'll usually find 2-3 but you can usually tell the chick is crazy. Sadly, messaging men first reeks of desperation, and when your profile says "seeking marriage" it's an automatic NOPE. I figure that's the type of thing you bring up later......Not even why seeking marriage is an option.
