As long as both partners needs are being met, then there shouldn't be a problem.

Personally, I couldn't be in a sexless marriage. The need for emotional intimacy is very important for me and just cuddling don't cut it. My "Love Language" is words of affirmation and physical contact. Because of that, cuddling feels like keeping me at arms length; close enough to touch, but not too close to have to let the walls down.
