so the stupid condom broke and i'm freaking out. it's pretty disturbing to look down and see the entire lower half of your body covered in cum when your not expecting it. 
I've never had this happen before, I'm always really careful so it must be the condom it was one of those Trojan bearskin ones which he wanted to use, but apparently they're pieces of shit and they're so thin I couldn't even feel the difference when it broke although I bet the fucking bastard noticed and didn't say anything, really it's his dick I don't see how he could not tell. And then the fucking baby looked like he was about to cry so I was the one comforting him when all i wanted to do was get the fuck out of there. Oh and I left so fast I didn't have time to stop in the bathroom and rinse off and all I could do the whole way home was think about his stupid little sperm squiggling all over me. So all in all it was a pretty shitty night. And now I have to go get god damn plan b in the morning.

And finally here's my question, when can I get tested for stds and have it be accurate, Am i right that if i got something tonight it wouldn't show up on a test for a little while?

Yes, two weeks for most STIs and 3 months for HIV.
 
I don't know if the guy supplied the condom or not but I would advise NEVER to use condoms that clients supply.  I only use condoms THAT I AM HAPPY USING and ones that I know cant have been tampered with before I arrived. 

Yes, two weeks for most STIs and 3 months for HIV.

For HIV, that's being ultra cautious with older generation (two generations old, actually) blood tests or thinking about the less accurate mouth swab or similar tests. Today, if a clinic talk about three months, just tell them it happened then, and as long it was actually over a month ago, the result is very likely to be correct.

what my Nurse at the GUM suggested was to always dash to the A & E and seek any post Exposure treatments available.

It's worth reading up on the pros and cons ahead of time. As a man, I think I wouldn't have PEP for unprotected vaginal sex unless I knew the man was, or was highly likely to be, HIV+. The cost is too great, both in terms of the experience of taking PEP and, here, the financial cost, and the risk is much lower than anal. If I were a woman, I might think differently.

If you do want PEP, you want to go to a clinic now - the later you leave it, the less chance it has of working and after 72 hours, there's no point.

Hi, recently I had a guy contacting me when and if I do test myself regularly. I said yes and obviously I have record of my testing. I did one last week and my results were negative. Last night I had a guy that said the same to me, but this one says he doesn't remember when we've meet like an exact date and I don't have any record of his phone number in my phone or my agenda. I was thinking I should test again but I don't have any symptoms of anything and my last results came back negative for everything.
Any thoughts in this?

I'm not sure I understand what you're asking?
