Why I Don't Like Longere, but Every Time I Wear Longe, He Can't Come

I'm in a serious relationship with my boy friend. He would casually mention that he likes fish nets, stockings and other types of lingery. So one day id langere did, whatever. One day i decided to wear it for him. Everything went great, until we were having sex and he couldn't come. H oh. I feel ietish for being flacid, for not finishing a fetish where i don't finish. Yes, imagine that. I like to go limp um to be cocked on day. My god. Please help.
