New here

Hello everyone I am not sure how this whole thing works here but just saying hi. My wife and I just got married in April and have been talking about having a child together for some time now. We have 4 childen already (15, 13, 9 & 8)  but this will be our 1st one together. I love the idea of having a large family. But I am just worried because this would be my 1st time using a sperm bank (we are a same sex couple) so it's a little harder for us. Just wondering if anyone else has gone through the bank to have a child?
