I faked once or twice and it always left me feeling miserable. I finally started recognizing when I just wasn't going to cum, and now I freely admit it - "hey, I'm not going to cum, but we can keep having sex if you want to". It's up to my partner to decide how he feels about a solo orgasm. Willingly giving my body for someone to use for his pleasure is slutty and submissive. I've found both reality and enjoyment in a sex life that includes the occasional night of honesty and no orgasms.
