What are a man's rights where having children or terminating them is concerned?

Effectively nonexistent.

If you are smart (and at your age I wasn't either), before you boink a chick... envision marrying her, having her raise your children, and growing old with her.

If she doesn't fit the bill... don't do her.

This is the foolproof way of not having to deal with the problem personally.

Of course... it seriously impedes your action, and doesn't work well with beer goggles... but, life is fraught with dangers and pitfalls.

Once you donate the sperm... you pretty much have exhausted your options.

Those are the rules and you have to win or lose by them.

If men were the ones to get pregnant, abortion would be a God Given Right.

EDIT: If you really want kids, adopt an embryo and hire a woman to carry it to term for you. Problem solved!

A man has the right to keep his zipper up.

A person with the gear to be pregnant and carry to term cannot legally be considered male; so your question is moot.

It takes two to make a child.
