Any advice on how to make sex more comfortable?

Lauren
I won't get too personal in this. 
First of all, I'm a lesbian and I am willing to use the natural conception method with a donor. 
My problem is I have a low-lying cervix and male penetration can be too painful for me to bear. I want us to be able to both be comfortable. 
If anyone has a less painful method/position to suggest, please help. 
What do straight women usually do when they have a low cervix? 
Please help with any advice you can. I'm actually rather scared that my TTC experiences are going to be extremely painful. :c
