I have had sex with a total of 4 men. All different lengths and sizes and I still can't feel any pleasure. I've tried different positions, foreplay, everything. I get arroused and I can pleasure myself but when I have sex I feel nothing. My boyfriend says that I come but I don't feel it. When he inside me its like I'm numb inside and its starting to get boring to him. I don't know what else to do. Any help?
