I am 19 and made a huge mistake, I was walking back one night very drunk and a ladyboy came on to me,she mainly masturbated me and very briefly sucked me off, all without a condom! I then mainly wanked her off but also sucked her off for maximum 5 seconds, again no condoms! She then came in my hand but because I was so drunk I forgot to wash it until the morning. Am I at risk at all? I am extremely worried and also have a girlfriend, what should I do?
