To many people, this might not seem like such a big problem. My boyfriend and I can have sex / make love for hours and he just can't come. Well, we only see each other at weekends due to work commitments and the first time we have sex is no problem. But on subsequent times, he just can't cum. He says he doesn't mind and really enjoys the sex but I feel bad because he makes me cum so much and I want to return the favour! Also, and this sounds really awful, it gets boring after a while! I can't really cope with having sex for more than 30 minutes or so. He's very well endowed and it can get quite sore, as well as a bit boring. Once i've cum a few times, I just want to stop.

He says he's never been able to come from a blow job, though masturbating on his own is fine. Though he's stopped masturbating since we've been seeing each other as he says he'd never cum otherwise!

Also, sometimes the head of his penis gets really over sensitive, almost painful. Sometimes i'm giving him a blow job and he flinches, like he's in pain. He says it's not painful but just unbearably sensitive. I wonder if the two things are related?...

Also, he has a minor back problem. He's had a bulging disc in his lumbar spine area for a while now. He's getting physio for it and it's getting better but I wonder if this could be a factor?...

We have a wonderful sex life and are really open with each other, talking about what we like, don't like etc etc. I'd love it if he could cum more often, if for no other reason than we might be able to get out of the house more often! He's very highly sexed anyway and not being able to cum just means he has a perpetual erection. I'm pretty highly sexed myself but am struggling to keep up!

Any advice, thoughts or suggestions are gratefully received. Thanks
