Please help identify what's wrong with pleco (white worm coming out of red swollen area)

If I am correct that little white worm may actually be the plecos penis he may be a male. The red patch around the opening may be a bacterial infection.

plecos take a long time to sexually mature, I think the previous comment is correct, so , lets not be tampering with his daddy parts, LOL. It doesnt really look infected, he does have a similair coloring on his fin .
