Josh2227 saidI just don't really understand this. Seems like only older men ever hit on me and never the younger guys. When i try to talk to guys my age, i just get ignored. I know i am kinda short and young looking for a 21 year old so maybe thats a reason? I have no idea! Would like to hear some thoughts on this! Thanks.
Could be many different things... It's not a problem unique to you, personally I do not approach guys under the age of 25 because I recall how awkward and uncomfortable it was to be that age and hit on (usually they were persistent too).
Wanna make them stop fast? Tell them your personal philosophy is that if they can't find something attractive enough about a 40 year old to make them date one, you shouldn't have to either.
Gets the point across fast...but then again it is rather rude also.
and as far as reasoning, i lean towards men using it as a way to try to lie to themselves about their actual age and whats expected of them at this stage in life, almost related to a Peter Pan syndrome.
