round painless growth just below glans

had this for a few months, went to my GP about it and they didn't say what it was but they were going to prescribe me a steroid cream for it but then I told them I've had genital warts before and they decided against it. they told me to just leave it and get in touch if it got bigger, started hurting etc. it hasn't really gotten bigger and it doesn't hurt but I have no idea what it is and it's worrying me. I would just make another gp appointment but it's impossible to get through to them at the minute. is it a genital wart? what worries me is it doesn't look like other warts I've had.
