Help! Suddenly aggressive dog

Sooo, it all started when a new roommate moved in. My 1 and 8 months old pekingese used to be super friendly and craved attention and love from everyone, even strangers. However, at the end of summer, I got a new roommate. Since he is a man, I thought that it may be some sort of testosterone fight going on since my dog is not neutered yet. However, he's now biting everyone who tries to pet him, even people who have been around since he was a puppy. He's never bitten me, but I'm now stressing out everytime someone approaches it. I know that my behavior is triggering it as well, but I can't help it. The dog has actually bitten someone it went to play with, so it's not even due to unwanted approach. He goes near someone, tries to play, and when they pet him, he immediately turns aggressive and bites.
Please give me some suggestions. Apart from this he is the best dog ever and I don't want him to be put down due to his aggression.

Have you had him vetted? Sudden behavioural changes are often linked to pain/illness. Otherwise I would say what you need to do is practice, practice practice. Once a dog learns that biting works, it uses this as its go to for any situation in which it feels uncomfortable. So if he growls at you, don't back off or take your hand away-don't increase the pressure either, just don't let him know that the threat of aggression is enough to scare you off.
Otherwise, find a SUPER great motivator (cheese works great for my dog) and bring your dog into stressful situations with new people and have them toss the cheese at him. Don't have them approach and give him the option of being aggressive, just make positive associations with everyone and everyone- do this especially with your roommate if you think that's who your dog's primary issue is with.
Also, get him sterilized ASAP! If it is linked to this, the longer you wait the more time the behaviour will have to set in and become inherent!

Are you sure that it is just a coincidence that this behaviour started when you got a new roommate? To change behaviour so suddenly is a little strange, to say the least.

It might be worth checking what goes on when you are not there, and the dog is with your roommate. Maybe you could get someone to drop in unexpectedly at various points during the day?

I'm not saying that there is anything amiss, but it is worth eliminating the possibility. Dogs' characters can change, but to change so suddenly....It makes me wonder, at least.
