Looks to me to be the perfect size for all activities. I love to deep throat but have a small mouth so I can't fully swallow a really thick one. But with a cock no larger than ~ 1.75" diameter I can make 8" disappear and bury my face against his stomach.
I also enjoy being fucked, and although I haven't been in a quarter of a century I do have some pretty good size dildoes I use in solo sessions. So as for the size of your lovely cock I would say you could satisfy me in every way without a doubt, and vice versa if you were inclined that way.
Don't listen to her, she isn't worth losing sleep over to have said that to you. I *do* have a rather small one, and have been with many many women in my life and only on a couple of occasions could I tell I really didn't satisfy her, but none were ever mean enough to point it out. When it comes to satisfying a woman in bed, some do prefer large or extra large, the the majority of women will tell you there's more to it than having a super-size salami.
