Am I the only one??

I am very happy for everyone who is in a great relationship, but as I read the posts I see post after post of how great their man is and how they have sex a million times a week, am I the only one who is too tired after work to have sex?? I get home at 6pm with my son and I cook clean etc..finally eat my dinner and crawl to the shower and get in bed for 10pm..don't get me wrong we have sex..just not a lot..I guess I'm quite envious 😂
