Sex probs with hubby?

I feel like prior to today a week ago my husband and I were having sex issues in terms of me always asking him and him always coming very quickly.
Hes really tired most days from military work and etc but indont want to be left and untouched.
 any ideas or help with this? :(
Made me feel unwanted and at raretimes i would cry if he came quick because i felt like i wasnt being pleased enough at all...help?
