Hello,
It can be due to dry
masturbation. Infection,
injury due to masturbation due to bad methods.
Will it effect for this year even though it never happens again later on?
Ans: no it won't if you do your masturbation properly.
Now I still masturbate like crazy and the next day it is sore but not too much?
Ans: maybe if you can able to lower your intensity during masturbation, won't end up damaging yourself.
In order to make it sure that I won't be sore again, should I lay off masturbation until it heals or until the sore is gone or should I get a doctor to check it out because I got tiny blood a year ago?
Ans: yes you need to stop masturbation for a few days so your vagina can heal . also you can use moisturizing lotion to heal faster. Yes, you need to see a doctor if its not healing.
Hope I have answered your query. Let me know if I can assist you further.
Take care
