Dating identical twins, can one love them each identically?

Some time back I read an article on conjoined twins (back before they found ways to separate them), and it spoke of how at least one found a wife. I wondered how that worked because the other twin had to go on all of the dates because he was attached literally to his brother. Some guys I knew was saying it would be better to date identical twins because you can have a de facto threesome with the same gal. Logically I can somewhat follow that, but in actual practice I guess I can’t. Even though they are identical twins and would have much in common physically and personality wise, they would not be the same to the smallest iota. That being said, is there any way a guy, or gal, dating identical twins can love both absolutely the same, if they can’t how would that affect the threesome?
