Sex- Ovarian cysts causing pain!?

Laura
Hey everyone! I was just seeing if anyone else has a similar experience to me. I found out I have a cyst on my ovary last summer. (Not sure if it's progressed or what) My doctor said it's benign and not to worry. Besides cramping here and there when my period is nowhere near being due, I've noticed it's changed my sex life. 
I have pain during sex, especially when my boyfriend penetrates me deeper. Also, I notice the next day after I have sex, I have period type cramps that last several hours. 
I want to know if anyone else can relate to this. 
Thanks!
