Can a herpes infection and weak immunity increase HIV risk?

Hello doctor,

I have a question regarding co-infection of HIV (human immunodeficiency virus) with various other diseases like syphilis, herpes 1, herpes 2, gonorrhea, hepatitis C, hepatitis B, chlamydia, CMV (cytomegalovirus), HPV(Human Papilloma Virus), and molluscum contagiosum.

Some time ago, I had a paid unprotected oral sex encounter but vaginal sex was mostly protected. I say mostly protected because the condom was very loose due to my erectile dysfunction. I received oral sex from her without any protection. Please take into account that prior to this episode I have been experiencing chronic penile sores and burning in the urethra supposedly due to my established herpes infection (earlier tested positive for both herpes 1 and 2).

I also have a weak immune system because I suffered from malnutrition while growing up. I have four questions that I want to ask. Would my herpes infection affect the window period for HIV 1 and 2? Would the window period for any of these aforementioned diseases be affected in case of pre-existing or simultaneous co-infection with another STI? Also, would my herpes infection increase the likelihood of getting infected with HIV or any other STI (sexually transmitted infection)? Lastly, please advise when should I get tested for all these STIs in order to have conclusive results.
