The best way to divert your (sexual) thoughts is to involveyourself in vigorous physical activities or sublimate in some other creative activity like music, dance, social service etc. I am 28 years old got married last month and within a week I noticed some pimples and blisters around my vagina. In all probability the blisters (pimples as mentioned by you) may not be due to a disease. They may be due to excessive friction to the genital skin during sexual intercourse. Till the blisters disappear do not have sexual intercourse.
