Is it normal if i showed myself masturbating via webcam?

I am a straight man but single since a lot of time.
I started to show myself via webcam to strangers for joke, but when I was turned on I felt pleasure in showing me naked. Obviously, I never showed my face.
The fact is that I become so turned on in front of the webcam that I'm not interested to who is watching, even if they are men. This because in these websites there are few women,so I masturbated me in front of other men.
Is it normal to get horny even if men are watching? Is it normal to have pleasure if people of the same sex of you are watching via webcam?
Serious answers please.
