As it warms up (for those in the northern part of the world), her wanting to be close to you can be negatively impacted. You can make closeness more likely by being sure you not smelly or sweaty. A fan can also make closeness a lot nicer – a ceiling fan over the bed can be a great investment.
Amen to that! Just a simple 20 dollar fan that gently blows air over the bed can do wonders for her mood.
