Just keep stretching - it might hurt, but do it gently at first, then as you get more used to it, add more tension, and hopefully in time it will get looser and less painful. Then if you can, try sex without a condom once you're a bit more used to it, and then hopefully over time it will loosen up.
I need to re-stress that what happened to me wasn't it tearing and ripping completely apart, more like a very slight rupture. There was some blood, but like I said it healed up within the same day, and now its less painful, and no less sensitive with respect to pleasure. I think it was just one of those things that needed to happen, it may well be the same for you. Just use your penis as you desire, and it should adapt to the stresses and strains you put on it. I've no doubt you'll be able to sort this problem out since you've made great gains which suggests you have a very adaptive organ there.
