Hypothetically: let’s say a man is complaining to a female colleague about his neck pain and offered a massage

First of all, I'm not giving any coworker a massage. I do not like any of them that well. But in the unlikely event they are dying and only my massage will save them, if they kiss me I'm not going to kiss them back for certain.

Kissing is not an exercise.💆. If she wants to kiss you, she'd do it anyway,even if their is no neck massage.

Forget the kissing tell her your groin hurts and if she goes there you will know she wants you

About as fast as the letters H and R can be said

By being one smooth mother fucker

That is such an old trick. Most of us are on to things like this. Take her out and have a nice talk. if that is what she wants she will let you know

You both would have to be after that from the start.

A kiss to thank her for the massage? Or maybe she felt that his lips/tongue needed massaging?

LOL well maybe ask her out

So much wrong with this question.
