Question: Are gopis celibates?
Answer: There are 2 types of srinagar rasa that culminate into transcendental sex. First is sambhogeccha mayi bhakti and another is tad tad bhava icchatmika bhakti. Although it may appear that sex here does not let gopis remain celibate, they in reality still are celibates. Why? Because there is no desire for personal sex gratification. The desire is to please Krishna, not their own senses. Celibacy for vaisnavas translates into Yukta Vairagya or doing everything only to please Krsna.
This is what gopis do. All kinds of oxymorons exist in the spiritual world. Perhaps, that is why it is a spiritual world.
