Is this an Std

I have got some painless boils under the head of my penis and I am freaking out, can someone confirm help.

It would be easier if you had a picture of what it is you have.  You need to upload from a PC / Mac or Laptop.

What size are these boils?  The size of a pea, smaller, larger?  Do you know how you got them?  Have you been doing any rough stuff with your penis?  Have you been trying to enlarge your penis?

I would love to put the picture up but since I am on a holiday I don't have my laptop with me, I did have sex in Thailand 5 days ago but was wearing protection the only time she took off the condom to give me a hand job but she licked it when she did that, so I'm not sure if it's from there or just the humidity in Thailand either way, I am currently in Singapore for a few days but I'm just really worried. Is there another way to show you a picture?

PS. Thanks for the prompt reply

No other way of showing a picture as you cannot load or view from an external site.  Perhaps you could describe what you have a little more?  Have there been any changes in the last few days?
