At my bachelor party, the stripper put a dildo between my legs and had "sex" with it for a 30 or 45 seconds. Then, she had me put the "clean", unpenetrated end in my mouth. It was a really long dildo, and most of it didn't penetrate her vagina, especially where I bit down on it. She had me bite on it, then she sat on it. She didn't get at all close to my face/mouth, as I mentioned the dildo was unusually long. There are conflicting reports as to whether or not she sanitized the dildo before putting it in my mouth, after she used it. She did, however, sanitize everything else she used that night in front of me, I just don't remember seeing this, I was really drunk. My question is, should I be worried about exposure to STD's or HIV? It's been almost 4 weeks and I've had no symptoms associated with an STD. (I had no open cuts and didn't lick or suck the dildo, only bit down with my lips open)
