"phimosis" is mean the redundant prepuce
HUH? I'm not understanding your post at all. What is "phimosis"?
The easy way to assess if you've had a risk and need testing is by using the following list as a guide. These are the risks for HIV that would warrant testing. If none of them applies to you, you have no worries.
1. UNPROTECTED vaginal or anal sex
2. Sharing IV drug works
3. From mother to infant (Unless you're a very smart newborn, you can rule this one out)
