Its normal, even a little cliche of you, to like your partners twin. Just, you know, be careful not to hit on the twin accidentally.

Can you fall in love with both twins?

Most identical twins agree that theyve never fallen for the same person, whether or not they end up marrying other identical twins. Segal finds this puzzling. I suspect that twins often really are attracted to the same person, but once one twin partners up, the other backs off, she says.

Can twins be attracted to each other?

Just as one might expect twins to fancy similar people, so one might expect their partners to feel a parallel attraction: that anyone who fancied one twin might also be expected to fancy the other. Again, Professor Lykken has found this not to be true.
