Hey, Robyn. If you click on Forum and then type something in the search field like "pump intimacy" or something like that, it will bring up every response and discussion with those search terms.
Also, we have a group here specifically on diabetes and sexuality for women. It is by invitation only, but I believe you can request an invite.
As far as the issue with your boyfriend, I think you're right that he needs to talk about it. Have you considered disconnecting during intimacy? That might make him more comfortable and many diabetics prefer that. Or perhaps you could wear your infusion sets somewhere non-obvious (like not on the front of the abdomen) during times you plan to initiate activity. Out of sight, out of mind, right?
In the end, this is something he can and WILL get over, but he needs to be able to be honest with you that it freaks him out right now. Many spouses and partners get concerned that they will jostle your setting, but I've never had it happen in my nearly ten years on a pump. And if it does, so what? It can be replaced.
He needs to see that it makes you so much healthier and gives you freedom, then its intrusion into your bedroom can be viewed as a necessary evil...until he no longer notices it or cares. The diabetes is an unwelcome intrusion to you, too, and he needs to know that this period of adjustment since your diagnosis will pass eventually.
