The question as I understand it, do you go out ? And why not if not.
I think there are as many answers as there are people ... but you can distill those down to one main reason: fear. Plain and simple, if we didn't fear bad reactions and we thought we would be accepted, many many more would go out.
The good news is that once you do go out, you'll find that it isn't as bad as you thought. In fact, most of the time it is just fine !
