This is perhaps the first question an individual questioning or perturbed by their sexual orientation might ask. The question or frustration may begin as a noticeable lack of interest in the opposite gender along with either a subtle or an overt interest in member(s) of the same gender.
Being homosexual is simply persistent or recurring sexual, affectional and/or romantic attraction on a long-term basis for member(s) of the same gender as oneself. Physical, sexual acts may or may not accompany that attraction. You can be celibate and still know your sexual orientation-–be it lesbian, gay or bisexual.
But physical/sexual acts between members of the same gender do not make the involved individuals necessarily homosexual, or lesbian, gay, bisexual, etc.
