Is it normal to grade every guy you have been with?

so i had a bit of an odd question asked earlier. When you have sex, do you grade people as in:
1. shouldnt have even bothered
2. good sex
3. oooooh sex?
or do you not bother at all? or do you use a different scale?

also, do you compare everyone youve slept with? if you have really great sex will u always strive to have that again?
