Ways for girls to stimulate herself

may i suggest the shower head or vibrating tooth brush both work well

YES get some help from a GF if you have one

First try humping the side of you bed until you get a orgasm. Then wet the end of a hair brush (the end you don't put in your hair) and just stick it into your vagina and then pull it out and then stick it in again and repeat this many times getting faster and faster until you feel satesfide (or you could just finger yourself) This works for me and it usually feel AMAZING, so hopefully it works for you. Good luck!
