How to get him to go crazy

Allison

So my husband and I have been married 7 months. He has changed jobs since then and been under a lot of stress. By time i see him in the evening he is wore out from work and weekends we wre busy a lot. Anyways lately like he doesn't really start sex much and most the times if i start it he goes soft or he just isnt fullh hard. What can i do to spice things up or why do you think he isnt getting hard? I have talked to him a bout it and he says its nothing to do with me that hes just exhausted but even on the weekend when hes slept all night its still like that.
