I've noticed over the past two weeks, that a couple of little spots have appeared on my labia and one between my vagina and anus. These spots first felt like tiny bumps beneath my skin, and I didn't really notice them as being odd. The past few days though, they've become raised, and are each a couple of millimetres in size. I checked their appearance and they're skin coloured, but are causing me irritation. The one nearest my anus is especially sore after going to the toilet.

I read up on STDs and i don't have alterations in my discharge, i don't have unexpected bleeding and my partner and I were originally clear or STDs. We had unprotected sex a couple of months ago (I am on the pill) and i've not experienced any soreness or burning until the past few days. My labia also appear slightly swollen and inflamed with some redness, but I put that down to shaving irritation.

I'm quite uncomfortable at the moment, and I am worried that I may have contracted something somehow. Does this sound like an STD? If so, I'll go to my nearest GUM clinic...

Thanks
