Back scratch

It’s so cold here and my skin has been dry. I asked my husband while we were laying in bed if he could scratch my shoulders. So he did and then proceeded to reach around and start grabbing my boobs. Tried to take my pants off. The whole time I’m thinking to myself “I didn’t say I wanted sex. I’m not in the mood for sex”. But as usual he talks me into it. Why is it to men touch of any kind means sex?! It was late and I was tired from Motherhood all day. I wanted to sleep and I didn’t want sex. Yet I get talked into it. I feel bad if I say no. I don’t want him to feel rejected. I want to be a good spouse and connect. All I wanted was a shoulder scratch. Why does it always have to be sex?!
