Anti-Anxiety and Orgasms

Just • Mommy to Oliver
Hello! So I'm on the Mirena and taking Anti-anxiety medication. Unfortunately it has made it EXTREMELY difficult for me to have an orgasm. It's putting some stress on my relationship with my boyfriend. He feels like he's failing because he can't get me there, and I feel bad that he feels bad. We do a fair amount of foreplay and the sex is lasting longer and longer. I didn't have an issue before being on the medication. I was wondering if anyone is going through the same thing or might have some advice? I'm desperate at this point. Please and thank you!
