Every relationship is different. What brings people together intimately and keeps them devoted and committed is different for every couple. There is no wrong or right reason for deciding to date someone and knowing the particular challenge ahead of time helps for you to be able to deal with it if it ever becomes a problem.

The only issue I would think could be a problem is if you hide the fact that you feel the way you do from her. I think it's fair that you get to ask the question whether or not it's ok to date her but I don't think it's fair that she doesn't get to ask the same question before deciding whether or not to date you. What I mean is, she needs to know what she's getting into also and without all the information you've just given here, she' would I think, assume you are attracted to her also.

Please consider this.
