Welcome to the forum! If you haven't done so, stop by the introduce yourself forum and say hi.
I think the first place to start is seeing a video of you benching. Post one up if you can. I have actually dealt with some shoulder issues in the past.
I think it would also benefit to post up your whole routine. In my case, it hurt to bench, however bench wasn't the cause of the aggravation. It was other exercises that were causing it. Maybe we can identify something that could potentially be a problem.
