Well you are only 24 years old, I wouldn't give up hope yet! But you do have to put yourself out there, if you are not meeting men where you are, branch out into new experiences. Also I know you are independent but if you prove yourself to be so self assured that you don't need any help, maybe they don't feel needed in your life? Men like to feel needed in that way-have them check the oil in the car, lift heavy things, even if you can do that yourself. They also like the chase, so maybe don't sleep together at first?
