I think everyone has a different view of romance.
DH and I do typical romantic things for each other quite a bit, we'll take it in turns to book a restaurant for a date, or a spa or a night away.
I'll go get him a Starbucks coffee he said he liked when he's having a stressful day at work
He'll find and order me leggings with pockets in.
I'll rub his feet as we watch t.v.
He'll give me a full body exfoliation.
But on a smaller level we continuously say positive things to each other, I'm going through a really rough time at the moment and every day he tells me how proud he is of how I'm dealing with it, and picks something he's specifically seen/heard/noticed.
We never go a day without saying we love each other.
And "expectation of sex" I hate this idea. I hate the "expectation" that sex is something men want and women do under duress almost.
I actively want, and seek out sex with DH because I fancie him, I love him, I feel more connected after sex. It's not a "gift" I give him. It's something we share, exclusively with each other.
Also a silent walk? That would be awful.
