Before I begin, I am typing on my phone. I apologize if the sentences don't seem in order.
That said, I feel like there are many factors involved in choosing
For example, in the ideal circumstances, there is some form of attraction
Be it physical, talent or mental (e.g. sapiosexuals).
However, being that we are all part of this website...the ideal kinda goes out the window. It depends. If you just want someone to donate then its pretty standard. Clean, healthy, will want minimal to no contact with child or in some cases, available to donate again in the future.
If you seek a coparent then things become as close to looking for a partner as can get. For me, my teenage to early adult years (HS through college) pregnancies among my peers was way too common but to quote jurrasic park "life always finds a way."
In the end, you decide who is the right fit. Asking questions and having conversations in my opinion works. I have donated to couples and single women before in some cases they just want the juice and bye bye.
I apologize for the lengthy reply but I just feel there is more to this than just the old "oh pick me! Pick me!" Write down what you want andbwhat you are willing to compromise (e.g. does the man have to be 6ft or is 5'11" ok)
As for me, feel free to message me and I will be happy to answer any questions you may have the my profile does not answer for you.
Have a great day!
