Maybe 'perv' was too strong of a word, but I don't think you need to advertise sex to make a good sale. A good lookin' girl in nice attire or modeling some kinda product, but no reason they have to be in a thong or almost topless sweating their buns off to make up your mind for a business decision. In a man's cave or in a backroom will work, but in our shop we have ministers, nuns, religious people, wives, daughters and other female participants and I don't want them thinking that's all we have on our mind. In fact, I don't want to even give a hint of it. It doesn't belong in the work place. Do I find it good to look at ?? Sure, I'm not dead, but I don't approve of those kinda gimmicks. A strip joint or Frederick's underwear place, that's different, but then again, I don't go there. Not because of the advertisements, I just don't need to.
There are so many ways to get your point across without stooping to basically naked women to make a sale.
