I'm not a musician so I can't accompany myself. Sometimes others will kindly accompany me, though I find that difficult having always sung alone. Being able to adjust the timing, tone, sound & notes as and when I want to makes me prefer to present an unaccompanied song. I've been told that people listen (I have my eyes closed usually so I don't check) and they're real quiet & apparently they clap afterwards, but I get so caught up in the feel of the song that I realise I'm only singing for me. Selfish ain't it :-)
