I usually finger her with one and then later two and then three fingers to get her opened up. Then I'll start to stretch my fingers slightly inside her, touching her walls and stretching her and smearing her juices everywhere.
Also. I finger her while she uses her magic wand in forplay. I hold my hand palm up and she put the head of the magic wand on her clit against the palm of my hand. I then tap on her g-spot and massage it with vibrating fingers and she usually haves 5-8 orgasms that way before I mount her.
Actually, her inner muscles are spasming then and it's harder to push in. But she's so delerious at that point, I think it all feels good. At least at that point I don't hurt her. Her vagina feels pretty soft and stretchable, and it's certainly slippery enough, after all those orgasms.
But we are every other day lovers at best. I never thought of it ini terms of her hurting the next day, but she's always had a rule about that and now I can understand it from her perspective. When you're that big, a recovery day is required, unfortunately. My wife gets uti's after sex a lot. It seems from other posts here that that is another symptom of a guy being really hung.
