HELP!!!!

My man and I have been in relationship for some time now...........but lately we havent been intimate because either he is too tired or it takes him forever to come to bed. I love him dearly and would never want to hurt him but i have been so sexually frustrated yet i know searching for fullfillment in an another man is not the right answer.....but what do i do?!!!! Can anyone offer any good advise as to what i should do???? How do i get his attention and let him know that he is not meeting my needs without hurting the male ego ?
