Many more women are finding they don't need a male figure in their life to have children. they are calling on so called "Sperm-banks" in order to becom pregnant.
Which is completely ******ed on the part of any female who feels that way, because regardless how they go about it.. it's the male's sperm who
MUST get them pregnant.

Silly Women, no wonder we used to club them during prehistoric years.. I'm about to find a club right now and start a history lesson.
None the less, I get what they mean by feeling they don't need a male (in their life) to have a child. But still, point (albeit silly, was made)
This is often used for lesbians, or women who feel their biological clock is ticking.
I think it's very respectable for Lesbian couples to do this, but the only problem I have with that is.. (from my opinion) half of the lesbian couples out there.. are experimental and only lust-related, not love. Therefore, some of the "couples" who suddenly wanna bring a child into this world, might be somehow misguiding the understanding of love to lust. That could hurt a child's up-bringing.
Women who's "clock's are ticking" need to 'shit or get off the pot'. That expression is more than old. Once again, most female's (through my opinion) that feel their 'clocks are running out of time' are only in that position because they've mainly been so picky in life, they've wasted a lot of years on worthlessness and stubborn nature.
However, there are a shortage of donors at the moment.
I can't find a bank, that's likely one of the reasons.
This conicides with controversy over whether they should remain anonymous. Many feel children should be able to find their father when they reach the age of 18. This is putting many men off, as they don't want to have many children running around that they'll find out about years later.
This would be a huge scare risk for many Males. The main reason is understandable as well.
A sperm bank is nothing more than a quick way to earn money for a male, in agreement to give out sperm that they DON'T have to be responsible for.
All the sudden, 18 some odd years later you get your seed knocking at your door and suddenly having all these "issues" with why you weren't in their life and they grew up with Two Mom's. Children who get put in this situation love to place the blame ON the male for that.. when the agreement was.. "no strings attached".
I'm not saying a child doesn't deserve to know who their Father is, but I am saying it's completely and 100% wrong of any child to willingly take out 18 some odd years of hatred on an unknown guy who had NO idea his 'seed' even produced a spawn.
What are your opinions on them? Are they ethical?
When you ask about it being 'ethical' that's really touching some tough lines to cross. Personally, while I say it's a justifiable option to use and it DOES help Female's without a counterpart to find happiness through a child in this manner.. it's still borderlining the idea that you're giving up YOUR seed, willingly knowing you don't have to take any responsibility for it.
I think that falls into some type of catagory of being irresponsible to a degree, but at the same time not.. if that makes any sense. Like I said, it's a tough call and a borderline decision to say whether it's ethical or not.
On one hand, through the positive side of things you're quite possibly helping to bring happiness to a would-be Mother who couldn't have a child any other way. (this includes some Married couples, who's Male counterpart can't produce so they seek this option)
But on the other hand.. it's hard for me to say that it's MY seed, and I'm willingly giving up all responsibility for it. That's almost the same in knowing you have a child out there, but willingly just walk away without wanting to give it attention or responsibility.
Would you ever be a donor?
The money you gain from doing it is definately enough for me to think about it. And yes, I admit with how I feel regarding the "seed/responsibility" it's hard for me to even say I'd think about it.. but Money is the source of almost anything.. you need it to continue, and when ends aren't meeting..
Knowing that in doing this you at least COULD be helping someone to be happy might just be the better deciding factor than believing you're giving up responsibility or concern over your 'seed'.
I would consider it, but obviously the Wife would have to agree and even in a joking sense when I found out you could earn up to $500.00-1,000.00 (I think it was) I said I was doing it.. and she flatout shot that idea down.. so in the end, she's wearing my Pants and telling me no.
Should they stay anonymous?
Honestly, no. Every child has a right to know who their Father is, regardless. I just feel that in this situation, an "astrisk" needs to be made next to the situation in which is says the Father had NO idea whether the child was actually born or not.
Because I'm 100% against the idea of an 18 (plus) year old teenager coming to my doorstep and cursing me to no end, all because "I was never there" for the spawn I never knew WAS there.
