What we are talking about here is celibacy, the deliberate choice not to have a sexual partner for any period of time. There's nothing ambiguous about that. Being celibate entails sharing NO sexual acts with a partner: any kind of intercourse (vaginal or anal), oral sex, manual sex, and so forth. In other words, no physical, sexual contact with others; meaning any genital (penis or vulva) touch, with mouths, hands or anything else between you and someone else is off limits.
