I only want to be matched with other gay or lesbian members.
Oasis.com doesn't have a single option to describe a members sexual orientation. If you are seeking members of the same gender, then update your seeking criteria, and choose 'Seeking Relationship' and select the same gender.
To refine your matches more accurately we advise you do not select the 'Seeking Friendship' category at all, as this will end up matching you with members that may not be looking for the same type of relationship as you.
On the search page, you should always select either 'Males seeking Males' or 'Females seeking Females' and then choose 'For Relationship'.
