This guy has made multiple posts about no risk, non-exposures in the past few months. He posted about seeing blood in a sink at a recreation center two weeks ago (same username), has posted questions about risks from sticking his hand in a dumpster, blood on his fingernail from playing basketball, and getting a haircut. His other usernames are sunsarethebest, sunsforlife, and others I can't remember.
I'm sure this is the same guy. He posted in the HIV support forum http://www.medhelp.org/posts/show/362159
using the sunsforlife username, which was an identical story to what he posted in this forum using the sidneydean username.
I feel bad for him because he has OCD which is obviously causing him to be obsessed about contracting HIV, but felt obligated to report the abuse of this forum by this individual.
