Yes because your guy might have some type of std that is causing it to get to your mouth. You should have him checked and ask your doc about it too. I think its genetal herpes or something, im not sure but it can get passed that way and you can get it too down there, get checked. To be safe.

That doesnt sound very normal to me I agree with nikki go get checked

Chances are ...It's not a fever blister....Oral sex with someone who has herpes can give you a cold sore like scab on your mouth....Please be very careful...This is very catchy......It can also be past down to your own are and this is a painful thing down there.........Check with you bf and ask if he has any sing of a sore at all...If so...This could very well be herpes.....Alway use a condom as it is not fair to other to give it to them....And do not give oral sex when you have a sore on your mouth or if they have a sore please be careful and be seen by a Dr.

He doesnt have any sores or blisters anywhere..

Well this might sound a lil gross, but, my brother and his wife-to-be both got tested when they had this problem. When she would perform oral sex she woudl wind up gettting "fever" blisters. Neither of them had any std's or aids. They wern't even actully "fever" blisters, the doc explained them as sores you can get if you've performed oral sex for a long peroid of time or like on a daily basis. Possibly that is the problem.

Herpes looks like small grapelike clusters of clear fluid filled blisters and the burn & itch like crazy right before they come out. If someone has the herpes virus they are most contagious when a sore is present, but you do not necessarily have to have a sore present to be contagious. You can potentially give someone herpes from about 2 weeks prior to an outbreak until well after the sore is completely gone. Also, someone can have the herpes virus in their system and never even have an outbreak ever!!! But they can still pass it along to others. Unfortunately, it's the gift that keeps on giving. Make sure if you do have a sore do not have any type of contact with others with that area until it is completely gone. There is nothing to rid the virus from your body but there are things that you can get over the counter or from your doctor to lessen the symptoms. I get "cold sores" whenever I get stressed, travel, overexposure to the sun. I just make sure that whenever I happen to subject myself to a one of those situations and a potential outbreak I take meds for a few days to try to keep them from happening before they have a chance to come out.

Fever blisters are herpes. I mean, some people call cold sores, fever blisters and both are herpes. So, if he has herpes, then when you go down on him, you are getting them on your mouth. If they are in the very corner of your mouth, however, it is probably just your lips tearing a little from stretching your mouth around his penis.

I'm seventeen. and have had sex with a friend twice and after both times I got a fever blister.could it be something else or if I stopped intercoarse with that person will it go away?
