I went to a massage parlor the other day and was offered oral sex, which I agreed to. The provider wrapped my penis very carefully in sera wrap before going down on me. She was very careful and didn't perform the oral sex roughly. I had an orgasm rather quickly, maybe 20-30 seconds in and the sera wrap didn't tear or anything. I don't know anything about using the wrap and wonder how likely it is that I contracted an std. Thanks!
