Input: Text: so i hang out with a lesbian couple that i've known since highschool. they've always been really good friends, and i'd do anything for them that i'd do for any friend. i also find them both really attractive. 

they asked me the other day, quite unexpectedly, if i'd ever consider giving them my sperm. not thinking it through, i quickly agreed (anticipating some type of long-awaited menage a trois). 

we discussed that i wouldn't be required to take care of the child or pay any child support, but i would also have to be okay with never being allowed to tell him that i was his genetic father. i would be his 'uncle'. i agreed to all terms enthusiastically. 

the problem came when we started discussing the procedure, and i discovered that they were planning to do in vitro fertilization. this essentially doesn't change anything except the aspect of me getting a threesome. 

i'm really not weird about the kid thing, i guess nothing bothers me about it. but are there any legal complications or anything i might be missing? did i fu by thinking with the wrong brain??

TIFU by agreeing to be a dad.
