unprotected vaginal sex with gay man

[jcuriois]

I am a female to male transsexual and live as a man, however still have a vagina. I have had unprotected receptive vaginal sex with a gay man several times. He has ejaculated inside me at least once. I do not know his HIV status.
How risky is my exposure?  My last encounter was about a month ago and I have not been tested. Should I wait another month before testing?  Am I at high risk?
I generally do not have sex with men and this has happened about 4 times.

Thank you. Can anyone comment as to where I fall risk wise? I know unprotected strike 1, receptive vaginal strike 2, sex with MSM strike 3.

Seems like a lot of strikes

Post testing

The need for a repeat HIV test if still within the window period after a specific exposure should be discussed. Although fourth generation tests shorten the time from exposure to seroconversion a repeat test at three months is still recommended to definitively exclude HIV infection.

Patients attending for HIV testing who identify a specific risk occurring more that 4 weeks previously, should not be made to wait 3 months (12 weeks) before HIV testing.

They should be offered a 4th generation laboratory HIV test and advised that a negative result at 4 weeks post exposure is very reassuring/highly likely to exclude HIV infection.

An additional HIV test should be offered to all persons at 3 months (12 weeks) to definitively exclude HIV infection.

Patients at lower risk may opt to wait until 3 months to avoid the need for HIV testing twice.
