Re: Sex toys
It depends a lot on the sort of sex you enjoy.
Some of the artifical V sex toys (fleshlights, etc) are more stimulating than the real thing, but the psychological feeling may be much less interesting than real. Same for vibrators.
Some men find prostate toys make things much more intense, but many find the idea too disturbing to try.
Its difficult to tell since interests vary so much, but personally I find male sex toys only interesting in the context of a female-dominant scenario - "I'm going to make you..., " . Otherwise I find actual female bodies much more desirable.
If you broaden the term "sex toy" to include lingerie , handcuffs etc, then there are a wide range of possibilities, but again it completely depends on the person.
There will be huge variation. That makes it really difficult to surprise him (or women) with a new sex toy and get good results.
