im a 23yr old male (UK) and yesterday i had sex with a 40yr old sex worker. i didnt realise the condom had totally split until after i had ejaculated inside her. when she realised, she rushed to the toilet and looked as worried as I did and on her online profile she doesnt offer bareback or anal (and when i text her after she assured me shes tested monthly and according to her last test is clean - but do i believe it?). i also had her perform oral sex on me without a condom. she was also inexpensive (60pound for an hour)- do you think i'm at high risk of catching something (im also circumcised if that makes a difference?) it happened yesterady afternoon, so should i be running to a clinic to get those 72hrs or less pills that reduce the risk of the infection taking hold?? please help
