Sex while pregnant

Em

So I’m pregnant 19 weeks and sex has been super uncomfortable since very early on, almost feels like my vagina is full of that makes sense it can become quite painful and just turns me off the whole thing to even think about it at the moment. My partner is super understanding of this and so we haven’t been having sex but I’m so horny all the time and always was even before getting pregnant so I really do want to have sex. I guess I’m asking has anyone experienced the same thing and what did you do to cope any positions that you can suggest me on top is an absolute no go zone!
