I'm 27yrs old but yet vergin guy. I mastrubate twice or thrice every weak. But for d last few months I'm not getting proper errection and it is nither lasting longer. I have never indulged in any wrong thing. I nither drink nor smoke yet I'm unable to get proper errection even after watching porn movies. I want to get married but m quite nervous. Sometimes I feel like visiting a call girl just to test myself. Please give me some suggestion.
