I am at 38 yrs old and my wife is 34 and obese. The problem is that during foreplay she gets wet enough but after penetration she gets dry. Consequently it becomes painful to carry on. So we depend on lubricant. With lubes she comes faster than usual! I tried to figure out the solution. Could this be due to my small manhood with thinner grith? Or does her bulky body prevents her from being wet for long time? She has enough sexual desire.
Please help.
