I'm confused by your description. 'Blister' means bubble-like lesions filled with clear fluid, that you could easily pop open--not 'hard' bumps. My bet is that they are not blisters at all; that they are somewhat pink and shiny; and that some of the bumps have dimples on top. If so, you have molluscum contagiosum. MC is caused by a virus, often sexually acquired, and probably can result from oral sex; but probably not all cases are sexually acquired. It's not serious at all, and easily treated. Conceivably you have genital warts, but warts are rare in the pubic hair area. It certainly isn't herpes and probably not any other STD other than MC.
As to your anal symptoms, it sounds like garden variety pruritus ani. That's a fancy latin term, but all it means is 'itchy anus'--and you already know that! It's a very common problem, not sexually acquired, and often has no known explanation, and is easily treated with cortisone creams.
But these are only educated guesses. For both problems, the only way to know what you have and to get proper treatment is to see a health care provider.
Good luck-- HHH, MD
Yeah I guess they are not blisters since they are not that easy to pop up (and I havent really tried to do so), and they dont hurt at all . They do look like little pearls but I think they are going away cuz they keep getting smaller ..and its been more than 4 weeks now. An im am very carefilll not touching them because I dont want to spread them.
I was just worried that I had herpes bacause I never had anything like that before.
I read that is possible to get them from towels and i think I got them when I was in florida.
Puritus ani doesnt bother me that much because if that happens a little bit of cortizone fixes the problem.
Thank you for your answer.
