Unless you have committed to an asexual partnership, sex, sexual contact and touching kissing, holding hands, cuddling etc. are vital components of a romantic relationship. The frequency is of course, up to you and it s imperative that you discuss your ideas about it in order to prevent resentment. Rare are the moments when both partners are in the mood at the exact same second, but that doesnt mean that you have to decline their advances. Remind yourself that you will almost always get there after the first few minutes and that an intimate interaction of any kind builds connection and elevates your mood and health. Bear in mind that you are never required to say yes. If you truly dont feel it, the best thing you can do is to postpone. Just make sure that you initiate or accept within a reasonable amount of time thereafter.
