Hello Sir/Mam, Mere ling me tanab nahi ho raha he but morning me jb soker uthta hu to tanab rahta he, baki jab GF k sath sex krne ki bari aati he to tanab nahi hota but agar me vaigara ki goli khake sex kru to sex ho jata hu but usme bhi agar me break lu to tanab khtm hone lagta he. Also me 15 saal se hasthmathun krta araha hu 2 or 3 time in day but job me aane k baad weekly. ek or baat agar me porn movie dekhu to mere ling me turant tanab ajata he but thodi der k liye hi.
