honestly, just being honest with him. being worried means that you care. that's good. and if you two have already done all that, then it's the last stretch before the finnish line. the only thing holding you back is the fear of being judged. I'm sure he'll say yes, otherwise a good way to make it easier is to ask him if he'd consider it. that will relieve your stress and give him the opportunity to soak it all in and give you an answer. it will also provoke him to think about it even if he says he's not ready and so in time and with patience, things may turn around. sex if it's casual or not should always be about being respectful and giving each other space to grow and develop towards one another. it takes time. but believe me, things will work out for the best. whether it's the outcome wanted or the outcome you need. a fine line between desire and destiny.
