you can take a blood test for herpes after 4 months but if you know you were virgin and you only have received oral so far you wont get the first symptoms elswhere than your genitals then if you did get them in your genitals you could get them anywhere else cos that would be HSV-1 and hsv-1 spreads to different parts of the body hope this helps.
thx....but getting red bumbs on thighs n butt r they normal.....after oral sex......may be its just fungal infection by touching n rubbing thighs ........thx for ur comments...but how can i check to doc now cos the bumps r not present now.......can i check out thrugh blood test
if received oral sex if you get any symptoms you will get them at the site you had contact in not anywhere else from oral you can get herpes or syphilis but this is rare always if you get symptoms check them at gum clinic or your doc.
