I am single and "love" myself frequently. I have a collection of toys, including anal, nipple clamps and dildos.
Before buying my toys I found I needed intense clitoral stimulation to climax and this was even harder during self-play as I can be a bit of a wimp about pushing myself to the complete extreme of orgasm that I know I can have.
Touching myself a lot is a must - playing with my nipples and sneaky strokes of my clitoris. But I use my toys to reach orgasm in a variety of ways and it is definitely easier to push yourself to really intense orgasms when playing with toys.
I love to use anal and vaginal at the same time - this is seriously intense. Also i have Maia wand which is simply wonderful.
And lube can be particularly helpful while you are starting off and building up your arousal.
