Single red painless circle on penis head

Let me first provide some detail. I am a 20 year old male. I have had 2 sex partners in the past 3 months, 1 a month ago and 1 3 months ago. I have not experienced any symptoms until the day after I had masturbated and noticed a single red circle on my penis head. It appears to have a slight yellow under the skin but it is mainly red and painless. Also barely raised. However it does not fully look like a wart, more like a circle 3 mm in diameter that is really stressing me out. I have read a lot about genital warts and this is what I am scared of. I am uninsured and family cannot afford insurancesad

Also I had been very busy working for the past 3 days and had just showered today. If I stretch the skin I can see a yellowish point underneath the skin that would normally indicate a pimple but I don't know. It's not painful like a pimple and I've never gotten one there

Pics sorry if this is inappropriate

I'm not a doctor, but it doesn't look like warts to me. It's probably nothing serious, but why not see a doctor and get it checked? I had something similar, but a lot smaller and was diagnosed as lichen planus. Applied dermovate cream and now it's gone. If it doesn't go away, go see a dr. 

Been 36 hours since I noticed it, also it has a different skin texture and feels like loose skin. Hasn't gotten better.

did you ever find out what it was?

How do you post pics? Mine is similar but more of a circle around it.

This should help you add images:

If you're using a phone or tablet, you may need to choose the desktop/PC option in your browser, or if that doesn't work, you may need to use a PC or laptop.

Did you get rid of it yet? I have the same.

I have a red circle around the top of my c**k

How is it now?

I still have one

What did the doctor say I have the same thing just no yellow underneath 

My primary said it was nothing to be concerned about. Not an infection. Im just hoping it disapers sometime.
