You know, in movies, television, or books, when someone says "I'm asking for a friend" it's usually just a way not to say that one asks for themselves. Not that that would be a problem.
Now, as mentioned - adoption could be an option. Though the relationship Mother-Child needs a lot of initial bonding, and isn't always the easiest. Especially when the mother is fertile and fully capable of having children of her own.
The bond between a mother and a child she has carried for 9 months within her, is stronger.
Now from a social and ethical standpoint: in vitro fertilization is the most commonly accepted, through sperm-banks it can be anonimous so that one does not have to do anything with the sperm donor, if the "father" has an extremely low sperm count and incapable of reproduction in the natural way this could still wield some results. It also puts little stress on the man in the couple, as there is no sex involved.
From a purely psicological view point, for the woman, being impregnated via the natural way has the best effect (usually). Size doesn't really matter, it's not a size issue, and just because a woman has had bigger penises inside her, doesn't mean she can't enjoy sex with a smaller one (than the biggest she had) in future. Also it is said that not always bigger = better, with much bigger than usual penises, certain women do feel discomfort. Rumor has it that the middle way is the goal to success, in size issues.
Size issue appart - having an orgasm or not, well an orgasm is just as much a physiological effect as it is psycological. The psyche can surpress an orgasm up to a certain point, if this should be desired. From a purely evolutionary-physiological view-point, the orgasm can aid in conception. Though of course it
can also occur without.
The one thing
not to do, is do things behind the back of the other!
Having children should be a serious commitment on both sides. The way it happens should be accepted by both.
Also a one-time thing is not necessarily enough for a succesful fertilization. Though once again, it
can happen, doesn't mean it
has to happen. Most succesful course is usually to calculate the most fertile time of the woman's period (which covers approximately 3 days of very high fertility) and have sex at least twice a day, on each of those 3 days.
