Watching Her

I know its wrong and I shouldn't be doing it but I can not help it and I am going to be criticised for it,
I am watching my daughter when she is bending over in her short skirt I like looking up her bottom, when I am at home I wear loose fitting pants and no underpants so my erection has room to swell without being restricted, occasional she has no knickers on and I get the view up her crack, she is oblivious of me watching, the reason I am like this is my wife I is no longer interested in sex at the age od 43, am I the only dad who does this and is taking the wrong interest thinking of i****t, give me your comments good or bad,
