Anyone ever use a sperm donor? How will you explain that to your kid?? Is being a single parent embarrassing?

Ok so I have been thinking this over a lot, and like I said if I am not in a decent relationship by 25 I am going to get pregnant by a sperm donor (or have a friend impregnant me NSA). I heard someone say that in a study done that children born from sperm donors have a higher rate of suicide, I don't want my baby to commit suicide out of embarrassment from what I did.. so how do you tell your kid they are born from a sperm donor?? Is it embarrassing??
