First of all, you probably already know this...but if you continue down the road of having unprotected sex with other (multiple) men...HIV is likely to be in your future. Condoms are effective against HIV. Sex lasts a moment...HIV lasts a lifetime.
That being said....looks like you dodged a bullet in this case. A negative test at 2 months after your last exposure is a VERY good sign. Follow up your test at 3 months for a conclusive result. After you collect your result...it's time to commit to a safer lifestyle. Then, you won't have to go thru this kind of ordeal and stress again.
Best of luck.
