Hi all. I just had a chance to read this Blog and it is excellent. I definitely had the same fear of being trapped with first time intercourse and avoided the missionary position for this reason. We’ve found two positions to be the most comfortable and pleasurable in which I never have this fear of being trapped. First, concerning the “from behind” or “doggy style” position, this is our favorite, most comfortable, most pleasurable, prevents leg-lock entirely, and I have never felt trapped. Second, we have used the position with him on the edge of the bed and my legs resting on his shoulders. This, too, is comfortable as well as pleasurable for both of us and I am free, so to speak, and never feel a sense of being trapped that could accompany the standard missionary position. Great Blog!!!
