I would say masturbation through fingers are best because there is more actual vibration and temperature body.
Talking about me I'm 23, i started masturbating when i was only 12, i used to lay down on my back n splash water near vagina-lips, it always gave me intense feelings. I never used my fingers earlier than last year while i felt so turned on after getting kissed by my bf; although i never told him about this. Inserting finger in and out vagina is amazingly working for me. Other things i used Marker pen (use back side always), cucumber (small one), pen (don't ever insert cap side, its risky), finger, whitener, carrot and many more u need to take care that all stuff + your fingers are always properly cleaned/ washed. Keep cool things in mind. If u r about to sex or masturbate only think about good things no fear, no odd feelings. Think about your vagina and your boy/crush/love. :-) cheers
