first you have to decide what you want, and then you have to be realistic enough to get it. you can screen for anything, but you will not find something impossible.
for example,
you can't get a virgin who loves sex, unless you want a 13-15 year old (why else would she still be a virgin if she loves sex?)
you can't get a girl who's a 9/10, that wants to have kinky sex 3 times a day, with a loving sweet personality, complete loyalty to her man, cooks and cleans, etc. unless you're brad pitt. because a girl like that would be able to pick any man on earth and would probably never be single.
so you can get a girl who is extremely loyal, but prepare to deal with whatever it is that makes her loyal and give her whatever she would want in return
you can get a girl who loves having sex, starts fvcking you on the first date, and wants to fvck every day no exceptions, but be prepared for her to have banged a million guys before you
etc.
so figure out what you absolutely must have, and what you absolutely cannot tolerate first and foremost, then figure out what traits are associated with your desired traits and learn to deal with them. (for example, if you want big boobs, don't expect to be dating stick thin girls who weigh 110 pounds)
(NOTE: in this context can't doesn't mean it's literally impossible, it means that it's so unlikely, that you might as well expect to become a millionaire off of buying 1 lottery ticket 1 time)
