I am a str8 guy, but will admit I am cock curious. I have no desire to even know the guy that own the cock, but if it is a good looking cock, I enjoy looking at it. The glory hole sound like one way of doing it. My only concern would be STDs, as you have no idea what the anonymous cock's owner is or does, or has. As far as me using the glory hole, No, I would rather look my sucker right in the eye and enjoy watching her enjoy herself. After all, she wouldn't be doing it if she did not enjoy it. If I ever went down on a good looking cock, I would rather look at him and it while I was doing it.
