I am in the same league as you but trust me if you have a sense of humor you can be funny. I have had situations in which I cracked jokes and I didn't even realize it, because I was using pun or playing with words. So it not that you aren't funny it just that you need to be aware of it. That probably doesn't mean a lot. But go read some comedy books, watch some tv shows, and then when you are in the mind set make up some jokes yourself and write them down. Memorize and rehearse, if you really want to and need a confidence boost, host a comedy show for some friends ask them what they think, there is no shame in that.
Imo comedians werent born funny, they just gain so much experience from writing and cracking jokes that they know how to please a general audience, or individuals and now it comes naturally. It is an art and a psychology, to understand how people react to situation. It is storytelling with no punchlines but them coming back to fill the dots. That what was done in shakespeares a midsummer nights dream. <-- great comedy work that is.
You also have to be witty, and fast to respond to situations to make the best out of it, like wise watch some Mr.Bean, you will notice that he doesn't say a word and he is funny. That is called slapstick humor, it is the basis of modern humor, the pleasure we have from seeing people hurt themselves or other by accident (obviously no death is involved because then it is seriously), like old Charlie Chaplin comedy, this is not bullshit it still applies today. Most of are humor is communicated via our body language, and a lot of it is tone. You can say "fuck you" and be funny if you say is in the right way.
No naturals who are funny, I think it comes down to the fact that they simply don't care about anything. You might notice that fat people, or outcasts, are funny people. That is because they feel they need to validate themselves to girls or others, because they can't use looks or coolness or anything else. Most importantly they don't care, about what they say, they have a bad first impression anyway, so they have nothing to lose. Girls will either go for confidence or funny, so I think everyone stands a fair chance.
Lastly, a girls sense of humor is really messed up, they laugh at the most shitty jokes!
