Local trama: The activity of oral sex may provide enough trama to inner lip or cheeks that may trigger an outbreak of a canker sore or apthous ulcer. These are not infectious or caused by bacteria or virus, just body reaction to some trigger, like stress, trama, certain foods or food coloring or flavorings, etc. ...Read more

I got a canker sore because I bit myself. Is it still bad to give oral sex since I got the canker sore when I accidentally bit my lip while eating?

I got a canker sore because I bit myself. Is it still bad to give oral sex since I got the canker sore when I accidentally bit my lip while eating?

Oral lesion: If you have an open wound, you are more at risk of contracting an STD. As for the sore, is this something you get frequently? If it's herpes labialis (blisters on the lip) you could give it to your partner. If it's a sore inside the mouth it is probably an aphthous ulcer or traumatic injury and is not contagious. ...Read more

Well here goes.... so about a month and a half ago I gave oral sex with a canker sore in my mouth to a man I didn't know.... he said he's clean of hiv?

Well here goes.... so about a month and a half ago I gave oral sex with a canker sore in my mouth to a man I didn't know.... he said he's clean of hiv?

Risky Behavior: Giving oral sex with an active oral lesion is not advisable for you or your partner. Both of you should be checked out for any possibilities of disease transmission that you are unaware of. Your partner's statement that he is not HIV positive doesn't cover the gamut of problems you could both experience. See your physician and urge him to do the same. Herpes is easily transmitted! ...Read more

Make: Make sure you both are tested for hsv type 1 and 2. It was previously thought that type 1 was only localzed to the mouth and type 2 to the genitals, but that is not correct. Also consider the fact that your gilrfriend already carried the virus and you did not give it to her by giving her oral sex.
Take care. ...Read more

Hey doctor I had oral sex with a guy yesterday. I have a canker sore below my lower lip and I sucked him. Can I get infected with HIV? Should I get te

Very low risk: HIV is almost never transmitted by oral sex. One estimate is one transmission for every 10, 000 penis-to-mouth exposures, i.e. giving oral to infected men once daily for 27 years before transmission might be likely. Oral sores might increase the risk, but the chance is already so low that it makes little difference. You should have asked him about HIV status before sex! Yes, you should be tested. ...Read more

May be herpes.: You may have genital herpes. Although, it's unlikely that it would have appeared so soon (the day after) exposure (oral sex) since they is a period of time before symptoms manifest (incubation period). The average time is 4 days but may range from 2 to 12 days. You should see you doctor for an evaluation and definitely during any period when there is genital ulcers or blisters for a diagnosis. ...Read more

Referred pain: Lesions in the deeper part of the mouth may cause the feeling of pain in the ear. You may wish to see your dentist for evaluation of oral health. If it is not due to oral health issues, the next step would be consult an internist to ascertain the cause of canker sores and treat the cause.
