Is this a risk or not? I really need advice.

Thank you all in advance for your thoughts and support.  

Before this guy I have dated a few times came over to my place, I checked my mouth out. Did not see bleeding or taste bleeding or see or feel any sores. He came over and we open mouthed kissed on and off over about a 1.5 hour period at most. He said he was negative and tested two months ago and never has anal sex without a condom. I know him pretty well and based on my experience with him I trust him. However, he does perform oral sex on men though he does not swallow and I do not think he does this often either. About 3 - 5 minutes after he left, I tasted a metal-like taste in my mouth. I spit out and it was discolored though with no red dots or blotches in it. I do have gingivitis and before he came over I did use mouthwash but did not brush or floss my teeth for this very reason. It was many hours earlier that I had brushed and flossed.  Now, I am freaked out. I did not taste blood between us during kissing or in my mouth during kissing. That only happened after he left. Is this a risk? If so, why? If not, why? My fear is that if his mouth was also bleeding (he has very nice teeth and takes good care of them) and he was positive then I could get infected that way as my mouth was not in perfect condition either.

Thanks so much for your support and help.

Kissing is not a risk, open mouth or not.

Hi Teak.  I did not have oral sex with the person.  We made out (open mouth kissed) on and off (maybe 50% of the time) for an hour and a half.  Thanks.
