A brahmacari is good for living a life of celibacy, but a person who can live a life of celibacy in the presence of a beautiful and obliging wife is more than a brahmacari.
Of course anyone who is stuck up with only one wife is also called brahmacari. You will set a very good example if both of you agree not to have sense gratification anymore and still you remain as husband and wife together. This is possible, however, only if both of you are fixed up in Krishna Consciousness activities.
