Erectile dysfunction due to lamotrigin and sodium valproate because of epilepsy?

Hey people, recently I started to have relationships with a girl and I can't get a steady erection, I'm epileptic and take valproate and lamotrigin.

I want to know if there is a relationship and if there is a recommendation to help the sex life.

It was a shameful moment but I hope I can survive it. I was suspecting this medication for 20 years affected me somehow and I don't know if it's permanent, maybe it's just a stress issue
