Look, in the unlikely event you really are asking for Miss Manners style social advice, rather than shit-stirring to amuse yourself , allow me to assist you.

Dear Brilliant of Mumsnet,
I was distressed to hear of your predicament. Sadly, based on your own account of your behaviour, you clearly have no idea how to conduct social interactions. Sadly, it is my task to explain to you that you are engaged in behaviour which we in the etiquette business describe as digging your way to fucking Australia.
Fortunately, there is an easy solution right at your fingertips. Don't do it. Talk about the weather. Ask what they watched on TV last night. Say how useful the report they produced on XYZ potential client/merger/acquisition was. Loads of things you can talk about without mentioning their appearance.
Fine to find someone attractive. Most of us (who are not asexual) do, from time to time.
However, the only circs in which it is okay to mention it to them is if you are in a social situation - bar, nightclub - where it might be okay to flirt. Even then do not do it as an opening gambit. Try the weather, the DJ's choice of music, the dreadful wine selection as openers. Ask her name first (you'll be relieved to know that it is no longer necessary to wait for a third party known to both of you to introduce you in this day and age). Only if the woman responds with interest to your overtures may you compliment her appearance. And do it once and once only - if you get a brush off you move on.
The only circs in which it is okay to mention that you find a woman attractive to a third party is if that third party is a really good mate, you won't be overheard and you are 100% certain the mate won't blab about it. And even then, if you do so in terms of "phwoarr I'd give her one" you are what used to be known, in a more genteel age, as a bit of a cad.
Sadly, however, based on your letter, in your case, I'd say you show signs of such severe social impairment in reading social situations that you'd be much safer leaving it to the woman to make the first move. If none of them do, then consider trainspotting as an alternative hobby.
Kindest regards,
Miss Manners
