From a woman's perspective, what would cause most guys to want to constantly TEST another guy?

I know I shouldn't be asking the opposite sex but I'm curious on how gals would view my situation

I hav gotten "TESTED" or "SIZED UP" by MANY dudes whether they were very attractive or not or very good with woman or not

I'm an "okay" looking guy but I'm not popular nor good with woman

So it baffles me that I'm sized up by many guys when I'm not scouted out by woman or seen as a "catch"
