I had received 5 blowjobs from different people, three other strangers I just met also gave me anal sex yet I was sure I used condom during anal sex yet when I received blowjobs, it was unprotected. It has been 3 weeks that I haven't masturbated. Days after my last blowjob, I'm pretty sure I haven't felt any symptoms and signs of having STD or STI. One time when I was doing my pooping, I was really shocked when I saw whitish liquid came out on my penis, I smelled it and it doesn't smell like semen though it look like semen. Is this a sign of having a particular STD. If I am going to get tested, what would be the procedure required for me to get tested. Thank you for answering my questions.
