A common misperception is that men merely want sex, or later on, someone to keep house
for them or "a nurse with a purse". Well, plenty of guys, including me, do NOT
want that. We are not all out to take advantage of you. In fact, I am concerned
that they would take advantage of me.
Ladies want someone to take them to dinner, be a
gentleman and ask for nothing in return, except conversation, and many senior men will
oblige and do this. That's not my POV.
Just because someone wants to date a nurse, for example, should not imply it is
for health reasons, to take care of him. I got hit on another forum once for that.
To the OP, caveat emptor --online dating is very illusory.
