His and Her Health

After a recent night of lots of great sex, my boyfriend lost his erection in the morning as we were on the verge of having sex again. We had sex normally that night but he lost his erection in the same way the next morning - twice. He's completely spooked now and can't stop thinking about it.<P>We can talk about this openly and I've tried to let him know he's not letting me down, but he still feels so humiliated. I'm pretty sure he's just got a mental block about it now, but I don't know how to help him through that. The internet's full of suggestions for men to deal with performance anxiety, but there isn't much out there for their women to help them out. Any thoughts?
