I've read a lot in this website but my situation is quite different.
16 days ago I met a gay man and we kissed, but during the kiss I bite him and he got a fresh cut in his mouth and started to bleed, before he found out, I DID TASTE HIS BLOOD in my mouth. Then he went to wash his mouth, and at that time I didn't see any cut in my mouth and no sore on my lips but unknown condition if there's small cut on my lips. my teeth and lips are sensitive, when brush teeth sometimes it bleeds, and when weather is dry my lips sometimes bleed. After cleaning, he gave me an oral sex, though there is very little blood is his mouth which I cannot see when he spit my sperm, but blood still can be seen when he used napkin to wipe his wound inside his mouth. So should I concern about getting infected HIV? Should I need to get a test?
