I haven't been offered any push assignments yet, but I'd try to be open minded about trying new types of toys.
My problem is smells.
I had a bad reaction to Sil-a-Gel - the smell actually gave me a migraine. And I ordered a massage candle that I couldn't even light because I was afraid of the smell filling the house. If that had been a review item, I couldn't have reviewed it. Since I live in the UK, just sending it back isn't a viable option. So I've decided not to order, or accept for reviews, anything that's likely to have a odor, whether good or bad. So no jelly dildos, no bath or body products, no flavored lubes, etc.
The other thing is couples items, since my bf is long distance. I can only accept them if I know he'll be around in the right time frame. But we're hoping to move in together soon - maybe this summer - and I think I could convince him to do reviews for men's toys when that happens.
