Migraines and sex

Tia

I had a migraine and took some over the counter medicine for it which helped and than I had sex with my husband and bam instant relief. It wasn't completely gone because I cannot fully orgasm with my husband. He tries but it always takes me so long and I can't get outside my own head and it's just not possible. He jumped in the shower and I finished myself off and I'm good as new again. I feel guilty because my husband tries and he especially tried since I was in so much pain this morning. How do I get out of my own head and enjoy my husband? It's been 11 years now I'm beginning to think I'll never get passed this
