You know, for the first point, the concept of using sex toys in general still needs to be better accepted by society. A number of people may have a basic vibrator, but I don't expect the majority of people to accept easily the idea that some people have BOX full and have storage problems. However, if you spend more than 2,000 on a special sex doll made entirely in cyber flesh, I might raise an eyebrow.
About the second point, I do not think it applies only to women, I have had boyfriends who felt insecure about my toys and felt like their manhood was threatened. As a result, the box was never opened in their presence and they have never used them on me.
And I think that your third point is completely irrelevant to the subject. It is a negative assessment and generalization that you make about a woman's psychology and sexuality.
But,I love my Fleshlight
https://top10sextoys.com/best-male-sex-toys/ Best masturbation toy I've ever used, by far. The
Tenga toys are supposed to be good, too, but I don't have one.
Cock rings are great for use during intercourse. A good cock ring can make my dick incredibly hard, which can lead to different sensations than normal. I occasionally use one along with my Fleshlight, due to the changes in sensation.
Vibrators can be nice, but it's difficult to find one that really works well on a penis. I like using my
Fairy Wand (a Hitachi knock-off) on my penis. It can give me a really strong orgasm extremely quickly if I hold it against the shaft of my penis. There are some new vibrators out there designed specifically for use on the penis (such as the
Cobra Libre) but I haven't tried any of them yet.
And of course there's the entire world of anal toys, including prostate stimulators. But I'd probably ask him if he's interested before buying him a toy of that sort. Some guys might not like being surprised with an anal toy.
Just some suggestions and one good video from Youtube, that I hope will help.Good Luck
