about hiv

I am a guy from China. In april this year, I  had unprotected anal intercourse with a man,with ejaculation. we ****** each other without condom and we both ejaculated. After one week, He did a hiv test and hcv test. Hiv test is a antibody test of ELISA,the result is negative,and the hcv antibody is negative also.but I was still scared because maybe he was in the window period of hiv or hcv. Three months after exposure,in July, I went to Beijing Ditan hospital ,and had a hiv-Ab test of ELISA and rapid hiv test also. The result are negative. I did five times of hiv test for sure.and all the results are negative.I also did the hcv test ,the result is negative also.
So ,I want to ask,if I need to do another hiv test  at six months after exposure?three months are enough for me to produce the hiv-ab if I get infected?now I am so anxious ,help me!

Dude dont play russian roulette with your life!-if you had no symptoms,and you both tested negative then you need to give yourself a break-such high risk stunts may not be so kind to you in future.Please learn from this....
