If there is no problem with the urination then there is nothing to worry about and the urinary meatus seems to be normal. There are many ways of treating this excess skin but the skin of penis is very thin and hence careful planning of the treatment ways should be done.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Thanks for the answer. However I spoke about it with an other doctor and he said me that mine is just a slight gland variant and that it's not really worth for esthetic reasons and also a bit a risky area to work on. So I think I'll just give up on this.
