Is it normal to be disgusted/annoyed at my dad

Is it normal to get annoyed and slightly disgusted at my dad because he Oogles at women on T.V.? If an attractive woman comes on T.V. he will say something along the lines of, "She's hot!" but to me it sounds like, "I'd like to FUCK her!" He says it a lot and will say it over and over again too, and it's like he lusts after women on T.V., especially newscasters and sometimes it doesn't bother me, but sometimes i just get so annoyed by it. I am attracted to women in a different way. I like a girl for her personality as well as her looks, and i usually look for women that are unique or different. I appreciate a beautiful woman when i see one, but it's just different for me.
Let me give some background information. I'm 19 and in college and I'm a virgin. I've never really had a "true" girlfriend but have had a few flings before. I'm not the best at socializing, but i get along with most people. Most people will say that they like me as a person. I do have urges, and I often masturbate to porn to relieve myself. I don't see this as wrong or perverted at all, because lots of people do it and I just use it to relieve myself and feel better. It's a little embarrassing and it's kind of pathetic i know, but i don't care because it feels good and makes me feel happy for a while.
My dad is 56 and disabled and his teeth are fucked up pretty bad, so he can't really get any action from women. He used to be happily married to my mom about 14 years ago and they had 3 kids including me. I am the youngest. When he was in high school he was really popular, played football, and was pretty good at it. So, I know he was quite the ladies man.
Even so, i just feel like when he says those things about women on television and looks at them like he does it seems perverted. I really wish he had a lady friend and could get some real action and maybe would stop objectifying women like he does. If there was a lady in the house, i know he wouldn't say those things he says like he does. So it upsets me a little, but he would get mad at me and start getting all defensive if i said anything. For instance, the remote has a "still" button and when you press it, it makes the screen freeze like looking at a photo. He would use the still button to freeze the screen to "Oogle" at women's bodies/breasts/lower areas... You can imagine watching an elegant woman ice skating and then he freezes the television to look at her crotch when she has her leg in the air, and leaves the T.V. on that image until it automatically goes back to normal (about 5 minutes). This was so repulsive to me that i said something to him and he got really mad and defensive and said that's what the button was for wasn't it! So, am I being like a prick or something or is my dad kind of sick in the head? How could i encourage him, in a nice way, to not do that so much so as not to offend him but to still get the message across so he will understand?
