Why are you going to let your girlfriend have all the fun?
You should get this for YOURSELF!

Looks to be a good starter kit.
I would look at the classifieds here for a razor also. There are MANY GREAT ones that are reasonable priced.

I would want to learn to shave myself in case SWMBO ever got mad at me.

Not sure I want a teed off person with a razor so close to me. Lol
