Short answer: Yes.
Longer answer: Yes, because...
Crying after a loss is not a bad thing, in fact, I believe it's a good thing.
It shows a few things, one, you care.
Two, that you've put in a lot of time and not getting the reward you think you deserve is...ok.
Third, you must be able to get that emotion out without throwing things, hitting anything, or hurting yourself.
Tears are ok...they're good.
My kids have played a lot of different sports, my wife and I did, too and we all did or have competed. We have given it as much as we can, and we care. We wanted to win, not because losing would make us losers (ok, maybe that's one of my problems, but anyway), but because they are keeping score and if they do then it matters to win.
That gets me to point two. We put a lot of time and effort into sports, really anything, it doesn't have to be sports. By putting that time and effort into it and then competing during the event, if you do not win, it hurts. And it shows you are a competitor, not a baby.
Finally, with point one and two, when that time comes that you lose, it is better to cry than to hurt yourself, break something and show everyone how NOT TO deal with adversity.
Cry...cry it out.
Then get back to work so that you don't feel that again, which you probably will, but it's time to get back to work to improve.
And show that you are mentally tough that you can be down, but you will get back up again, and again and again and again....
