Well I'm a believer of having animals fixed. We have to many in shelters now. I have 2 males and yes I got both fixed and it made a BIG difference. Stoped the marking and the trying to run away and the humping. Your male is at a good age but I do have to say having them fixed doesn't always stop the marking but I worked for me. Good luck.
