For me its a case of acceptance. For me and I can't stress this enough that this is just my experience, its not necessarily going to be the same for you, but just knowing its okay to not be okay helps tremendously.
I have a very understanding and loving husband and that helps. I know I'm never going to be just like everyone else who has always had an easy sex life. So I just decided one day that that's okay. I don't need to have an easy sex life, I don't need to have what everyone else has, I'm different and its perfectly okay to be different. I just work at it harder. My husband and I constantly change what we do and how we do it. When things get hard we stop having inter course and mutual mastubate. We talk all the time. I have a freek out and that's okay too. I don't have to have someone elses sex life to be happy I just need to be okay with the one I have. Sometimes if that means we only use toys for a few months I refuse to feel guilty. He's getting pleasure and so am I and its in a way that isn't hurting anything. Then we go through periods of being crazy active Sexualy.
Like I said for me Its all about acceptance, I'm never going to be 100% okay, and that's okay. Once you've truly accepted that you start to see the silver lining. I kinda just said to myself one day "fine so I'm never going to have easy sex like everyone else but I'm going to damd well make sure I have fun trying everything to make the sex life I do have better." Then we started experimenting, what toys did I like what didn't I?
I have never had an orgasim at all until my husband not even by myself. So I took that and made that an achievement rather than focusing on the negative that I must be broken if I can't orgasim at anything else. Then worked slowly on it until I could make myself get off. Even if it was 1 in 10 times that was still 1 in ten times more than I had before.
Its all about just being okay. Knowing that even when you aren't feeling okay one day, know its temporary and even if it takes along time you will be again.
And above all never stop trying! Even when it feels hopeless! By trying even when you don't feel it it can reassure your partner that you won't give up and reassure yourself that even if you don't orgasim you've just been intimate and close to a person who you love and who loves you. Slowly by being okay with that everything just clicks and boom it creaps up on you and your enjoying it again.
Try a little bit of everything. And remember to laugh! Sometimes it makes it easier by taking the serious edge off it.
I brought glow in the dark condoms and he came bursting in the room wearing it shouting "WHO YOU GONNA CALL?" It was funny and took the pressure off. I couldn't think about anything but how hilarious he was and had my first O in a month because I was so distracted I wasn't thinking about how I probably wasn't going too!
Enjoy each moment for what it is and decide not to care about the one that comes after it!
In a nut shell I'm okay because I decide to be even when its a rough patch.
