I am a 29 year old professional in pune. I am 5"6 tall and weigh 77 Kg.I am hardly aroused by naked women no matter how attractive they are. I get aroused by their footwear(if its high heels more better), feet, nailpolish( green, black, blue, yellow) and if they are bossy its all the more better. Sexuality is inclined towards BDSM.Hence when having sex , I dont maintain my erection. I lose erection the moment i insert my penis into the vagina. and if the foreplay is not related tto the interests I mentioned then I dont get erect about 50% of the time. This is causing a massive self confidence deficit when I am with a woman. Please help me out
