I have used this many times with tremendous success.
I do not whisper it in anyone's ear until later if
the relationship has grown into an intimate one but
very often I will catch a man looking at me and more
often, then, without hesitation, I will say, "Yes".
Of course, the man will say, "Yes, what?". I then will
say anything from, "Yes, I would like to kiss you",
or "Yes, I have time to have a cup of coffee with you"
or "Yes, I have a spare 30 minutes and would love to
spend them rubbing your back", or any number of other
ideas which I have stored up for what I like to do in
the company of a man. "Yes" can lead to anything from
doing the dishes together to running a bath together,
to making out on the couch for an hour. I like to
savor especially the time when a relationship is new
and you are discovering what a person likes and also
allowing them into your space and uncovering, a little
at a time, your likes and dislikes.
I have a boyfriend now, and we have been in a relationship
for a number of years and my "Yes" still works. He lights
up when I am rushing through my life and he calls to see
if I can do something with him, and I say, "Yes, I would
love to spend some time with you.".
