I am a married man, i got married last june, so far i have done Natural sex with my wife twice or thrice rest of the sex i did with only Pills.like(Viogara,manforrce ,Suhhag raat ,satisfill Penagra,) but among all these i could say i got little satisfaction with Penegra, My wife doesnt know about this.But i am afraid that i might get side effects due to this. sommetimes my mind becomes hot or i get irritated,alight headache and diahharea, I just wonder why this happens to me.the other day one of my male friends happened to visit us from Gujarat. i slept with him and i told my problem.he began to suck my nipples aimmediately i got erection and than he sucked my cock too .he said there is no problem with my sex.,May be physcologial problem due to wife s attitude and behaviour. sometimes she is grumpy moody, wild ,Loud slowy..very talkative ,absentminded careless etc etc? is this so. so far i never approached to her for sex,but she forces so i go only once in a Month. by seeing her behaviour my mind soesnt click, she is too Egoistic.and sexy too ,,She is a divorcee too,,and there was a gap of twlelve years of her marriage? please advice
