When you’ve spent enough time with someone, you tend to learn about what is it they like or don’t like. The things that get them going and the things that put them off. But then again, assumptions are a deal breaker. Make it a point to find out if your conjectures actually fall in line with what they want. Even if it seems bizarre to you, your partner might find something pleasing. Be considerate of what they want emotionally and physically, and try living up to it. Happy partner equals happy you!
