I actually am a single mother of my own biological son. I know this may seem odd to most but, even though I may prefer to never have intercourse, I did so because I cared about the man I was with at the time and felt pressured to do so. This is not to say I didn’t want him, as I truly love my son. But you can definitely be asexual and have your own children. Of course, I’m hoping to meet another asexual some day down the road who won’t shy away from my circumstances.
