Odd Problem Around Base of Penis and Scrotum

Around the underside and base of my penis, and top of my scrotum, the past few days, a clear, sticky 'liquid' has been appearing. The area has also been slightly red and sore, painful to the touch and to the areas moving. It stings if I apply water to the area in any way. Sometimes the 'liquid' hardens, on both skin (and clothes it may transfer onto), forming a whitey-yellow crust, which on the skin makes it hurt even more.
It's since scabbed over, mainly on the topside of my scrotum, which stung like hell. After a couple of days, that all flaked off, and it started again from the soreness and weeping of the sticky 'liquid' through the skin. Only this time there is patches of dry skin and little bits of scab up the length of my penis, with a few raw red sores that look like they're going to bleed, but haven't yet, where the skin has cracked due to being dry/scabbed.
I'm 17 and have never had any sexual contact with a woman, but me and my girlfriend have been considering having sex and I want to know what is wrong, so I can try and get it cleared up.
