A little late to the throw up fest but vicky is completely correct medically speaking. This can be caused by lots of other things and can also be indicative of other issues. I am always extremely concerned when i see little to no restrictions in an sp's advert. It is like gambling at the casino, it is rigged and not in your favour.
Basic rules always apply and probably go without saying, no glove no love. Ladies do a dick check. while many infections can be difficult to spot take the time to really look. If you are unsure don't take a chance. Also pay close attention to the rest of the body, rashes, sores at the corners of the mouth. There are lots of good sites to get educated or just use google image.
I was at a sc in toronto one time and this EE woman looked awesome till she got close and i was able to identify herpes on her lips. Yummy (as i mentally vomit). She was quite busy though ... scary.
Anyhow didnt mean to bump the thread, but the source that started this in the first place must be very desperate to make a living. STI's can be uncomfortable to say the least i had one person i know describe it like "razors in my twat" their words not mine.
play safe everyone.
