Hey guys,

About three weeks ago I had a stupid unprotected one-night-stand with a girl on holiday. But I'm afraid that I caught something off of her. A few days before I had a cold but after having sex with her my flu got worse. I've also noticed that the colour of my sperm has changed, its normally thick white but now its a lot more clearer. The skin on my penis head has also started to peel.

Is this an STD? I'm only 18 and this is the second girl I've slept with. I know I should go to a clinic and get checked out but I'm too nervous and tbh I'm not really good at this sort of thing.

Would just like some advice basically, will all be appreciated greatly.

Cheers
Dan
