Help please! Abscess/Boil OR Herpes/STD??? (Pics included)

about a month or so ago, I accidnetally cut myself near my anus while trimming my ass area with clippers and it did bleed a small amount. it hasnt been red or hurting. i have used condoms for every sexual intercourse encounter I have had. Could it be a boil/absess from the cut, herpes, sphyllis??? . I am stillgoing to get tested for STDs tomorrow. any advice? opinions? if its a boil any recommendations to get rid of it???
