Sexual frustration

Well. Idk what to do. I have been married 9 years, and I have told my wife over and over I will gladly go down on her without expecting anything in return. I do not mean to to my own horn, but I know I get the job done. I was put on this earth to go down on a woman. In our nine years of marriage, I have probably been able to go down on her maybe 15 times? My drive is way higher than hers and honestly, it could be satisfied if she would let me go down on her every other day.

I know what some of you were thinking I am a lazy husband who just comes home and plays video games or something. But I do about 90% of the housework stuff. Hell, I even stopped putting away laundry to type this out. I worked a stressful 45 hours a week (i know a lot of you work a lot more) so I do pull my weight and then some. I am just stuck, divorce has crossed my mind, but I don’t know if I could justify leaving because our sexual compatibility is not there anymore.

Am I an ass for maybe wanting to leave because of this?
