Hi @jeff.mpp 
Welcome to the forum 
Have you tried any toys before? If so, what do you have?
I would recommend a bullet vibrator if you haven’t tried one before. As for penis extenders, I’m afraid I don’t have any experience. I would suggest going for one of the smaller ones unless she has used larger toys before. Going straight to a long, girthy one might be uncomfortable for someone who hasn’t used toys of that size before. There was a recent thread here about extenders which might have some useful info although I think it was mainly about the larger options but it might still be worth a read.
If you don’t get many replys on here you might like to start your own “introduce yourself” thread and put this question on there too. You’ll also get a warm lovehoney welcome from everyone else too!
