Is it normal for 18-21 year old men to hit on women my age?

@Donotfolowme Some are hot though.

@WaafaS Now having sex n relationship are two different things

@Donotfolowme How so?

@WaafaS Really? Sex doesn't require any relationship--as a woman, you can have sex with a vibrator or banana.

A relationship is a more rich interaction; and in attempting to have that, it would be unsurprising for you to find the "headspace" of an 18 yr old rather different from your own.
