during +2 i have male bestfriends of 3 who were generally 5,6 years old me i dont have bf.they used to give me gifts choclate not much expensive like 100,200 rs in weeks.after sometime they request me for s*x .i cannot say no at that time biggest regret . After that day i used to sleep every next day with each one with rotation .They stop me thinking as friend but treat as Toy after that .called me and they will take me and leave.NOw they all are married but i am alone crying
