Legal ramifications of providing Natural Insemination services (In Maine, US)?

Christopher asked:


Recently I helped a life long lesbian friend conceive her first child through what I term as, “Natural Insemination”. Yes I do mean sex, however for something she has wanted for many years, that being a devout lesbian has prevented. There was little sexual emotion and seemed mostly mechanical to achieve our purpose.

I say all this because she insisted on paying me for the favor, which I of course denied. I was curious if this would be sexual solicitation, if one was paid for a simple sperm donation? The answer I know is obvious initially, but she has other friends who request my services with much enthusiasm. I was wondering if there was a way to legally offer my services as they seem adamant to receive my donation over a clinic’s (which I have repeatedly recommended prior to this idea). There are no sperm donation clinics in Maine currently, and time is limited for myself as a pre-med student. Thus this could help my financial situation as well as a real job isn’t feasible.

Either way I would be curious if anyone out there has some legal advice into my situation.
In response to the kids possibly coming to my door and requesting child support has been considered. A binding contract would first have to be signed stating I have no responsibility in the matter. I also make sure the mother’s are financially stable and capable of raising a child (as well as going to a clinic to test for possible STD’s, and fertility complications). All I am looking for here is the possibility of doing this legally, similar to a sperm bank that some people refuse to use.
