Problems with intercourse

I have just recently entered into a new sexual relationship after being celibate for nine years.

I am 48 and he is 56. We really enjoy sex but we have yet to have full intercourse as his penis although erect is not very hard and when he tries to enter me - his penis keeps slipping out. This is really frustrating for both of us. Apart from that everything else is great.

I do carry a bit of weight but I don't think this is a problem. My new partner has had issues and surgery on his penis and is hopeful that is will rectify the situation. What I just need to know is why even though he is hard, the penis keeps slipping out. What are we doing wrong?

I think I've experienced the same or similar in the early days of relationships. Try not to get anxious about it, because it's probably a simple matter of getting acclimatised to each other's bodies, movements etc.
