It's quite possible you're not as funny as you think, or at least not funny to women.
Plain fact is that a lot of women are sexually attracted to men with a good sense of humor that can make them laugh. It's a lot more than just an enhancer of appeal. Ask a few women to name their top 3 traits they look for in a guy. I'd guess at least half of them will say they want a guy who is funny.
Actually it looks like 77% rank a sense of humor as their number one trait:

Hell, take it from reddit if you want:

I mean the evidence is overwhelming. Women find humor sexually attractive. We're not talking clowns here, we're talking a witty type of humor like I described. Usually sarcastic humor works best.
Anyways, the point is women like funny guys just as much if not more than they like smart guys or fit guys or good looking guys. The way your attraction to women works is not the same as the way a woman's attraction to men works. There are going to be some things you don't really understand but you just have to accept them. This is apparently one of them.
Oh... but wait... I should ignore what I read on the internet right? Instead I should listen to you and go off of your limited experiences because the internet is highly unreliable and whatever you say is solid gold and should probably be written down in some religious texts.
