Who can view the photos?
Generally speaking, out of respect for your confidentiality, heterosexual male members for example only view photos of heterosexual female members; and heterosexual female members only view photos of heterosexual male members. Heterosexual males cannot view photos of other heterosexual males and it's the same for the females.
Equally, men seeking men or women seeking other women can only view homosexual profiles in accordance with these same criteria.
However, when you register, if you tick "seeking men and women" (both sexes) you will be able to view profiles of those people who have made the same choice when they joined. You will thus be able to converse with members of both sexes. This has been made possible in order to assist those who genuinely wish to make new friends of both sexes.
