Thanks everyone for your thoughts on this matter.
I will be actioning them all !!!
I really appreciate your time spent on this.
I disagree with Marcus...if the husband keeps having sex with a prostitute, condom or no the OP will never be 100% safe having sex with him. Using a condom HELPS but it isn't 100% protection from STDs (think of it this way, condoms fail to prevent pregnancy about 16% of the time...if sperm can get through, HIV and other STds can too). A condom is better than nothing but only abstinence is 100% effective.
If the husband stops (and how is the OP ever really going to know?) THEN she can get a conclusive HIV test...but as long as the husband engages in such high risk behavior, they are both at risk, even with the use of condoms.
To add to this. You will have a conclusive HIV test after 3 months from your last unprotected intercourse with your husband.
go to the doctor and tell them you want to get tested for everything ASAP
I would also like to add that y'all may want to seek the services of a marriage counselor. (((hug))) best wishes for you.
