What is this? Is this an STD?

Me and my partner had sex for the first time since having our child, this time using a condom. Ever since we had sex I've been having discomfort in my vagina and swelling and burning that's constant. I don't know if I'm having some dermatitis from the condom? It is the first time using this brand. I have fleshy lumps already on my vagina from wear I tore giving birth.

Hi, how long has it been like this and what are your symptoms ? did semen or any of his genital enter you before he wore a condom ? was it scented or lubricated with spermicide or anything other than lube ?
