Big Penis but A Big Problem

So my husband has a big penis and i can’t handle it. Every time after sex i feel like I’m leaking.. We can’t do certain positions i used to love in previous relationships, such as doggy style or I’ll scream like I’m being murdered. So Literally after sex, all day, i feel little fluid squirts come out my vagina. After a full day it stops, until we have sex again and it happens. I thought it may be urine but it doesn’t smell like it. Idk. I’ve never experienced this before. I need advice. He is aware of this and it worries him. I went to two doctors my general and gyno and they don’t even know what I’m talking about. I went to a urologist he looked and said everything looks normal. I’m at a loss. I think i would feel better if someone went through this or goes through this so i wouldn’t feel alone.
