I don't know if this is the case at Nairn - don't actually remember which tees I played from when I visited you up there - but there is a reason why women at many clubs are reluctant to have men playing from "their" tees. That's because, frequently, the "women's" tees are very small and poorly maintained compared to the "men's" tees and they simply can't handle the increased traffic. Moreover, due to the shorter distance you find lots of men play irons from those tees so dig them up quite badly. Factor in, also, that women generally don't have separate casual and competition tees so they can get quite protective of them. Men's sections are generally many times the size of the women's so even a small proportion playing forward could be many more players than the handful of women playing further back.
