HELP ASAP

so recently I started noticing the skin around my penis was starting to irritate me. Now there are red marks on my skin, tiny white bumps and my penis and testicles are extremely itchy... What is it and what can I do to fix the problem?? Much appreciated

It could just be jock itch, but it's hard to say without more information and/or pics.  How long has it been like this, how old are you, and are you sexually active?

I'm 17 at the moment and fairly sexually actively. The last time I had sex was mid July but I always used protection. The pictures I took don't give a good indication as to what it's like because it's only a vague rashy red colour that might have only occurred due to scratching. 

It's been like this for about a week extremely itchy 

It's hard to say for sure, but my best guess would be that you've just got jock itch, in which case these links may help:

If an antifungal cream doesn't result in at least some improvement within 2-3 days though, you should consider seeing a doctor.  You could either see your GP, or if you're in the UK, you could go to a genitourinary medicine (GUM) clinic - google "GUM clinic near me" for details.  They're free, some places have clinics for under-25s, and neither a clinic nor a GP is allowed to tell your parents you've been.

If you do see a doctor, then if you could update this thread and tell us what they say, it would be appreciated.  Good luck.

Thanks a million man. The links are very helpful and yeah I'll keep you updated on what happens. Thanks again
