>Futa is better because the sex isn't boring
Oh even if you're a man, you can get into yuri sex. Watch at least a couple dozen lesbian JAV films from start to finish, read lewd yuri that heavily deals in words, read descriptive language, play with your own nipples until they become sensitive. Really, do your best to relate to females.
In the end though, if you're still anything like me, nothing will beat futa. The more I got into yuri, the more I got into futa. Those strange girls absorb everything feminine and then multiply it by cock.
