There are two separate issues here. The first is that you have participated in a number of high risk sexual encounters. This alone, in the absence of any symptoms at all, would definitely be an indication for being tested for the HIV virus. This is an easy test to perform, and if you go to see your primary care doctor
, they will be happy to arrange testing for you.
On the other hand, there is the question of what these light patches on your skin might be. It is certainly the case that the HIV virus can be associated with a number of different skin manifestations, including unusual patches and rashes. However, there are usually other symptoms as well, such as persistent infections, fatigue, weight loss
, etc. Therefore, I think casting a wider net and looking for other (more common) causes of skin findings would be in order.
When you go to see your primary care doctor, they will be able to examine your skin and help you figure out what these patches might be. They'll also be able to prescribe any necessary medications (such as topical steroids) to help you get the condition under control.
