Short Frenulum. Without surgery.

Till some years back, I had never pulled back my foreskin. Some years back, I came to know about it, then I tried the same but it was giving me discomfort and was painful. I thought I had phimosis. Although I tried for some days and was able to pull back the same in the flaccid condition but couldnt do it in erect comdition. Somehow, I kept going at it. Now I am able to do it but in erect condition, when the frenulum is pulled back, it pains in the frenulum. The foreskin also just uncovers the head and doesnt go further down. This results and pain and discomfort. Some time back i tried having sex for the first time but as I was about to enter I kept losing my erection, due to inherent fear of more discomfort due to short frenulum. Kindly guide as to how to treat it, possibly without surgery.
