Welcome to HCM,
Some exercises increase your abdominal pressure, and this will increase pressure on prostate
and seminal vesicles.
Thus, without arousal or erection some discharge from penis can occur due to increase in abdominal pressure.
But orange tint of discharge is not normal. It can be due to presence of blood.
Presence of blood in discharge can be due to injury
If it occurs next time, you should get discharge tested at a pathological laboratory and in case of abnormal report, consult an Urologist
