New Courting Disaster Question

There’s a new question on the Courting Disaster Web site.

My girlfriend (an attractive, professional, successful person) likes to hug me for what feels like an uncomfortable amount of time (often a minute or more). I think she tries to drag every one out into a “going away for a long time” sort of goodbye, even if we’re just milling around the house. How do I tell her this bothers me? Or am I just incapable of affection? –Please release me
