First, the basics. I'm 6', 175 lbs, brown hair, brown eyes. I'm a software engineer by trade in a family stuffed with university academics and engineers.

I have recently relocated to the Rugby area. This means further relocation is going to be impractical in the near future, but I've no problem with relocating again in the medium term if that's required.

For those interested in a sperm donor:

I come from a long-lived, healthy, family. Family history and genetic profile available on request. This includes whole genome testing, which I had carried out to see if there were any genetic quirks I needed to be aware of. I am reasonably healthy for my age. Medical history available on request, you can always ask for additional testing - this may take a little time to arrange and for me to pay for (I won't ask anyone to fund such testing, although I may ask for help if you want the results quickly and they aren't a test I have already taken). I won't refuse any reasonable request.

As far as I'm concerned, my main priorities here are to be the biological (but not legal) father of a child and to assist others in having a child they can call their own. As this is a role as a sperm donor, I'm well aware that the line is drawn there. This would not be a co-parenting option. In all probability, the child would never know that I existed. I would be fine with that.

(I'm obviously looking at other options, too. Any sense of legal or moral fatherhood would be through those.)

For those interested in co-parenting:

I have always wanted to be a father, but the opportunity has never arisen and I'm starting to feel the pressure of time. This is really my last chance at being a father, a dream I've always had that has never been realised.

Although I come from a long-lived family, so there's no reason to think I couldn't bring up a child, age does start to play a significant role and I want to have a child soon to minimise any age-related risks.

I feel as though I understand the demands on time, energy and patience that a child would place on me, although it's fair to say that nobody can be truly prepared until after it happens and I am willing to put in whatever work is needed to reassure the person I'm coparenting with that I can follow through on my side.
