Hi Susan,
It's a good idea to bring in someone as a support, even if it is your best friend (male or female). I'm married, but if I was going it alone I would definitely not invite any one of my three brothers. I'd much prefer to have my best friend.
Here are some of the issues that we have discussed with our known donor and our counsellor in Australia. Some of them obviously will not be relevant to you:
1) Counselling - what do we need to do to get approval
2) Legal issues: making sure you know where you stand (ie SD has no legal rights as father, however some sort of relationship with our child so that he/she knows who you are).
3) Disciplinary issues – we have the say in how to raise our child
4) Access issues to SD
5) Long term access to SD’s family
6) What happens if we move interstate/national or if you move?
7) What happens when you have a partner in the future?

How this will affect our friendship?
9) What would happen if we had a falling out?
10) What would happen if DH and I got separated/divorced?
11) What happens if we want a second child?
12) How will we feel if the child is disabled (in utero/afterwards)?
13) What if you have an issue you need to discuss with us as parents?
14) What happens if we pass away and you are still living?
15) What happens if we go through IUI and it doesn’t work?
16) What happens if we go through IVF and it doesn’t work?
17) At what point do we give up?
18) Family medical history (SD’s and Ours)?
19) Education of the child
20) What we have said to our families so far, and our plans to tell them
21) Our plans to tell the child.
22) SD’s concerns in general
24) Spiritual beliefs
HTH
