Not unusual at all! Understand this ok: our society paints this manly john wayne (an old but good famous cowboy) shoot'm up and ride'm hard gun-ho he-man or g.I. Joe mentality that is 100% false, got it!!
Men are just as sensitive as women but that is a lot to understand some times.
You just need to take your time -- as does the lady. Some time go w/ her and just spend time in a bed w/o sex. Don't make it the number one showtime, ya know.
Take it easy. Take your time, forget about it. Explain to her exactly your feelings, i.E. It's number one on my mind but it doesn't all work that way and that you really need to take it slow.
