LATAX and RUSTED RAZOR ALLERGY

Sarah
My boyfriend and I have been together for 2 years now, we never ever use condoms. We used it in the begginning for a month and stopped because it's not as pleasing or feels not right. Recently we have had sex & he is not circumsized so straight to the point the thin skin that holds the entire skin on his wee-wee broke off because I'm too tight. Even with lube and wetness. So we decided to cut back on sex for a little but it's hard too so he decided to use an old condom he had from the begginning of our relationship. Little did I know the condom expired the begginning of LAST YEAR 2015. He used it because the PRESSURE of the condom held his skin together so it wouldn't pull back. After we had sex I went to rinse myself and saw that I had red bumps everywhere. I was allergic and it was an old condom. Issue my entire vagina is swollen like I've never seen before. I can't even wipe correctly or sit in certain ways but the vagina has tripled it's size. And I have bumps all along the lips and labias which are quite big and I know this is not stds or herpes because I just checked myself 2 weeks ago and I passed everything and so did my boyfriend. The razor I used a week ago had rust on it but I didn't notice because I was trying to shave really fast but the rust could affect it. :( I used honey, neosporen and cleanse it about 8/10 times a day because of the pain irritation and itchyness it feels like it's scolding down there. Any advice please??? :(
