A lot of the time when my husband and I are having sex I'm super wet in the beginning and for about 5-15 minutes but that's it. After that I get dry and uncomfortable. My husband will go down on me sometimes if this happens and then we can go a little longer but it's so annoying that I can't "go" for a longer period of time. Honestly a lot of the time I end up taking full control to make him cum faster just so I know he is satisfied before I go dry! I get off too, but I hear so many couples going for an hour or hours! Any advice?
