I have been married for 2 years so you would think I know what to do to initiate sex

But honestly I feel very awkward and I have this underlying fear of picking the wrong time and my husband doesn't feel like it (which is absolutely ok) but it's a bit of rejection and that sucks

My husband has been my only relationship and sexual partner

Any tips or suggestions or advice to help me through this?
