My advice; have sex with HIM more! Embrace your spontaneous, sexy, love kitten side and pamper him with it. Life gets busy, we have other priorities, and sex can fall off the "necessary wagon" when you are tired or stressed. The way we keep it interesting and constant is by mixing things up. Although I have fulfilled almost all of my man's fantasy's, I know his sex drive will be upped by two things a) feeling better about himself (so I compliment him more, make him go workout when I do, and make sure I buy healthy groceries so he's forced to eat good food) or b) get his mind crazy turned on by making his fantasy's come true yet again. When my man is working out consistently and I make sex all about him, I get better sex, more sex, and more spontaneous sex. It's really an improvement for both of us =D Best of luck!
