I have a few suggestions...
I know you suggested home-made toys, but I find a story or two from http://lustylibrary.com/ can easily get me going. They're all clearly labelled - obviously some are incoherent and rubbish, but you can check how highly rated they are and some are really, really good 
Erm, as for toys...do you have an electric toothbrush? If so, carefully wrap a flannel/cloth around it and vibrate away (but don't, err, put it in you! and wash the flannel!) Otherwise, phones vibrate don't they  I'd really recommend getting yourself down to Ann Summers or similar. Or LoveHoney.co.uk is good for sex toys on the cheap AND discreet.
And orgasm is where you reach a peak of sexual pleasure.
Good luck!
