My favourite.... After a hot shower...dripping wet, walking down the stairs to where he is sitting and handing him the towel to dry me. Wearing only a t-shirt, sitting behind him on the couch, massaging his back.
Great question, actually. For years my partner figured that since I was the older one in the relationship... I should be the one to initiate. (Normally he's brighter than that.) Then we talked about it but patterns are patterns. We're also different in that he prefers verbal communication where as I prefer spontaneous body language.
Usually we're already in bed when it happens. Hands just start lingering and lips start traveling. Then it happens. Otherwise, it might be right after we wake up. Everything's still slow and dreamy and warm in the mornings. Naturally, we just gravitate towards the warmth. One of us leans into the other and hands on me tell me all I need to know.
I finally have a bf that matches my sexdrive. He usually initiates...sometimes its as simple as a look he gives me. Most often, he wakes me up and attempts to get me on top of him...I'm still half-asleep, so I resist and he ends up hopping on top of me. Lol. Eventually I'm wide awake and can take over. I love aggressive bottoms :-)
