There is nothing wrong with using toys with someone you love and want to give pleasure to. A toy alone works to make a person climax but they are so much better when you have another person there to share it with.
I look at toys as something that makes it a little bit easier to ring her bell. Sometimes it's about her desire to orgasm while I am inside of her.
My late wife found it more and more difficult to climax at all before she passed and I still remember her last one riding me with a toy on her clitorous. If I had been intimidated by a toy I wouldn't likely have that memory at all as it had been about a year before that when she had last climaxed which also included a similar toy. Being together was the most important part of it.

Learning should never stop for any reason. However you do have to temper your expectations when learning a trade or skill you can't use due to personal limitations. This needs to be taken into account but that is something an individual should weigh on their own with the people in their life.
