Howdy,
Personally, I think cause are all a little scared to get rejected, and while in the end it hurts if we do get rejected, but it's a learning process and "very normal." This can go for either guys or gals. Granted, I'm in the same boat, but I've learned to some degree, you'll got to let it go, and try or try again with someone else. While, I do admit it's easier said than done, but it's the best perspective to look at, IMO.
