[Toughy]

I hope you are being smart at this.....

*medical histories for your donor(s) going back a couple of generations..it can be truly important to know this stuff....

*legal paperwork around the sperm donor's involvement....money, religion, time with the kid once s/he/? is hatched, donor's parents involvement

you need to get this stuff in legal order or it will come back and bite you in the ass big time.....I've seen it happen.....it's not just him jacking off in a cup and you using a turkey baster to plant the sperm....

or if you are going to do it the old-fashioned way.....how is that gonna work and trust me it will have a big impact no matter what you think now...

what will the birth certificate say in the 'father' part?

be smart....seek legal counsel and get all the paperwork in order.....now before you get down to the actual business........I'm sure the UK has LGBTQ friendly legal folks who deal with this stuff all the time and work sliding scale if you need it....
