Just because one partner prefers a certain position, that's not a problem as long as s/he tries several others weekly. Variety is the spice of life.
I think if you're playing and experimenting, that's a sign that you have a better sex life. I think it's just that if you ALWAYS do it in the same position because that's the only position one partner wants, that's what the author is flagging.
Parents often get dressed quickly after or do it partially clothed in case kids wake up. Personally, it hasn't hindered DH's sexual performance and can in fact enhance it if both partners are flexible and have a sense (senses?) of humor.
I agree. I think the question is why you're jumping up to get dressed. DW jumps out to get dressed b/c she doesn't like her body and prefers to be covered.
Fantasizing about other sexual experiences is healthy and leads to other interesting scenarios to share. What's needed? More fantasy and exploration, not less.
I agree with your interpretation. I think the author was saying that if you're always fantasizing about being with someone else, that's a bad sign.
Honesty is always the best policy. In sex, it's the way to more fun.
I think that's the authors position, too, and I'd agree. DW won't open up about anything that she likes.
