I guess this is why tattoo parlors insist on customers being sober when they get inked. My contention remains that if the decision to sly or not to sly causes that much tension then it might be best to wait and see. But while you're waiting try to determine what the cause of the tension is, whether you, yourself, have a hang-up about sly and what you need to do with regard to that or whether you are apprehensive about the reaction you will get from others.
This brings to mind an old saying in men's psychotherapy circles having to do with the only 2 questions a man must ask himself:
1) Where am I going? and
2) Who is going with me?
And God help you if you get them in the wrong order.
