This is a good, hot story, but the two halves feel really disconnected. You've got him remembering the crazy, sexy girlfriend, and it doesn't tie in with him getting his rocks off at the gym. Seems like two separate stories mashed into one.
I would also establish a bit more Diane, and the other girl's attraction to him; perhaps they find out that he's single now? Maybe they have a moment? It just seemed abrupt that they would go straight from tormenting him to having a threesome in the shower.
