Hello Doctor, I Have Been Trying To Find Answers For

Hello doctor,
I have been trying to find answers for my situation for a long time now, so I really hope you can help me.
After I masterbate or sexual activities with my partner I feel weak it normally takes me two nights to get over it, this effects my football, if I orgasm the night before a match I will be extremely tired and have no energy and stamina, so I stopped. Unfortunately though this hasn't stopped the problem as I sometimes cum in my sleep before a match for example it happened this morning and I have a match this evening,
I would like to know:
If it actually makes you weaker or is it just a bad mentality.
If so how do I fix my energy levels before a match/how long will it take to go back to normal
What can I do to prevent cuming in my sleep?
Your general advice on my situation.
All help will be appreciated,
Kind regards
