Reply to Recording your own vocals and other vocal questions

Hey guys,

I have made a track and want to spice it up with vocals. The idea of having my voice on the track excites me and I really want to make it work. Problem I never sang and I am faaar from being a singer. oh and English is not my first language though I speak very well and only have slight accent. I tried recording my voice on my mac via Ableton and after EQing it sounds decent in terms of mixdown but i always feel it's so out of place! I know everyone believes their voice is weird and sounds strange but maybe you guys can share how you overcome the fear that you sound silly. The track is deep house so I will be transposing it down slightly and have very few sentences.

1. Any of your experiences with recording and adding your voice to tracks?
2. Tips on the writing lyrics?
3. Tips on approaching figuring out where the vocals would go when the song is ready?

Hope I make sense

Cheers,
