I don't think you necessarily do it for attention. I had a strong urge to cut my wrist last week (never have) but I was just like...um...that'd be too difficult to hide (no cat, work at a ER so would def get some side-eye). I think it COULD be for attention (and I say this cautiously) if you found yourself checking it out when other people were around in particularly, or consciously placing it in sight when people were talking to you - or maybe you were simply challenging yourself, glad to know just how well you were at keeping it under the table even in plain site.

In either case - neither is a problem! I used to think I cut for attention, until I realized when I was around people, i'd hide the area (although sometimes I feel that too can draw attention) and be very aware when they were around - but on my own i'd secretly admire it. I'm coming to understand that sometimes we do need attention; not continuous hugs, praise and excessive approval - but it is nice to know we matter to somebody somewhere. It's okay!

I don't however think you cut there for attention possibly, because you cut due to the urges not because you wanted to have them there for others to see later. So my final answer would be no, but I can understand why it would raise questions for yourself.
