They should understand what are appropriate expressions of love in a celibate context. Living a celibate life requires abstinence from sexual activity. Dioceses and religious communities, in working with candidates, look for behavioral evidence that celibacy is a possible lifestyle for a person.

Diocesan priests make no vows.
For ordination, they freely make promises of celibacy and obedience to their bishop.
