Hey y'all, so lately with masturbastion i haven't been getting off from just my fingers alone.  However I don't have any money right now (about to start a job, but currently have 3 pennies to my name), so I won't have any money for at least 2 weeks.  Anyone have any tips when using my fingers?  I also haven't been able to find my g-spot.  I've never been able to find it.  It's kinda difficult for me to masturbate pentratively because my nails are kinda long and I have to avoid scratching my insides.  I'm fine when it comes to clitoral stimulation tho.  I really need help.  Thanks to everyone who does help!
