I find the whole concept of romance ridiculous, and have never been able to create any character that even remotely cares about that stuff, there is a lot to do that is more interesting and important than wishing for, or trying to get in a relationship. Only time I bother with this stuff is if someone throws themselves at my character and they could see some benefits to this and don't despise the person. For a dream lover, it is just a dream, so there is no temptation because they do not actually exist (since my characters did not care to have relationships in the past.)

My dream lover is whatever random appearance I feel like looking at (usually some sort of drow or other elf, half elf, or tiefling) and can be male or female, same or opposite sex, same or different race to my character. When the game is properly released then I will most likely still do this, but attempt to have something that makes at least a tiny bit of sense for rp reasons.
