As with most things female, what touch she wants varies with her monthly hormone fluctuations. She may be extra touch hungry at one point, and touch averse a couple other days. One day touching her breasts is arousing, another it’s comforting, then annoying or painful. A given pressure is too much some days, and not enough other days. She may want you snuggled up to her all night at times, and feel “crowded” at others.
Keep this in mind, and try to mentally chart out the permutations. Some women are aware of the why behind these fluctuations, while others are not. Learning her patterns will make things better for both of you, but point them out at your own risk!
