This little thing is a great addition and as a couple we can both say that it adds pleasure for both of us! For a girl this feels great and seems to add an extra tightness during penetration which seems to create an amazing feeling on my g spot! For a boy it makes penetration feel tighter again when the girl has it in - but my man has put this in himself (after proper cleaning of course) and he said it unexpectedly felt amazing and added a new feeling he never felt before! This shows that the size is great for someone who is new to these kind of toys. The vibrating function is fun as well and it's so easy to use - would definitely recommend.
