Hi, I am a South African male who is circumcised and living in South Africa. I have had condom protected sex with 11 escorts and prostitutes, on my latest encounter I had unprotected oral sex (I received) and I also gave (by licking the clitorus but not licking the vaginal opening). I also fingered her vagina without any barrier, after this I had condom protected sex and ejaculated in the condom. Then I had condom protected sex again but when I was pulling out, the condom stayed inside of her, I am unsure as to whether or not it slipped off during intercourse but I pulled out and was not covered. I am going crazy with the thought that I might have contracted hiv or any other std... From what I have described am I at risk of any STDs??
