Really this is something you need to discuss with your partner, there's pretty much everything imaginable available these days. There's also so much to consider, everyone will have different preferences or may not be into toys at all.
Personally I go thru stages of using, getting bored, different preferences etc, your budget will also be a deciding factor, toys can be expensive but my advice there is like with anything, don't waste you and your partners money on cheap rubbish cause you probably won't use it.
Myself I like wands for extra stimulation, if you think it would get a lotta use best to get one that plugs in, nothing worse than having it die right when you're enjoying it, they tend to be more powerful too.
For insertables I prefer larger toys, again so much choice depending on what mood takes me. It might be peen like realistic, it might be shaped and knarly for maximum pleasure and a different experience, it might be metal and smooth, just depends. Whatever the design and size if you're thinking of rubberised toys then Myself I only enjoy the ones made from silicone, for me they just have a nicer feel to them, personally I wouldn't entertain the older plain rubber toys or the plasticy ones but hey, that's just my preferences x
