Men at work

I'm not easily shocked, but I was rather surprised by something a friend (let's call her Jane)  recently said to me.

A mutual friend of Jane and mine was having her garden remodelled and the work was being carried out by three young men. They were probably good looking, no doubt well toned (given the nature of their jobs), and certainly tanned because it was high summer. One hot afternoon, these young men were toiling away in our friend's garden, tops off due to the heat. Our friend happened to be at home and was clearly enjoying this spectacle because she rang Jane and invited her round for a cup of tea to view the three lithe bodies of display.

This seemed a bit much to me, really. I can understand noticing and quietly appreciating the spectacle by oneself, but inviting someone else round to, frankly, ogle seems to me to be taking things a little too far. If a couple of men did this to a group of women, it would be called sexist. So isn't it sexist in reverse as well? Or are our standards really that double?
