Hi all.. I am in a relationship since past 5years and we have been doing sex for 4 years. well thankfully i have never used a condom so far and we even last for around 45 minutes including foreplay. But we are now getting tensed as i cant stop doing sex. Each time we meet i get excited easily. I am tensed if its going to hamper our relationship in the near future. Plz suggest how can i control my overwhelming desire.
