I used to have this problem, here's what helped: 1. Reading up about how to delay ejaculation, there are many techniques. 2. Regular sex, let him practice lasting longer, sometimes just let him thrust and try not to cum. 3. masturbation and porn: This helped me loads, he must only masturbate with lube (closer to the feeling of a vagina) or actual sex feels too amazing (compared to a dry hand). Also, he should masturbate less often but for a longer time, and refrain from quickies, say, aim for at least 20 minutes a session Without porn... That's right, watching porn seems to make premature ejaculation worse over time, (at least for me) and I'd advise cutting it out completely (I think this is due to the dirty and vivid visuals from porn viewing dancing around in the brain when with a woman.) I've gone from premature ejaculation to pretty much choosing when I cum, and it's made sex better. Your bf sounds like me in the way he wants to please etc and engages in lots of foreplay, I wouldn't worry about about him stopping this, I still do all those things, just with the added thrill of long penetrative sessions. Also consider having sex more than one time in a session. He can cum and then have sex again in a few minutes time. (Perhaps surprise him by sucking his flaccid cock 5-10 minutes after he has cum until he is hard again) His condition can be improved, I am proof of this. I also think having a large penis comes into play with premature ejaculation, so if he has one then that is another reason for the PE. I'm quite large and when I've had sex there is a feeling of tightness and 'filling up' a woman completely, with more to spare, which is a massive turn on, + there is more friction at play too than with a normal sized penis. I hope this has helped, and I wish you well. Any questions feel free to ask :).
