Yes, as they say "it´s not the size of the boat, it´s the motion of the ocean"...
Moreover, do not forget that a lot of sexual pleasure depends also on non-penetrative stimulation, e.g. oral sex and manual stimulation which can make the sexual pleasure more intense and satisfying when it is done before or after vaginal intercourse.
It isn't what you have, it is what you do with what you have, that matters. Be enthusiastic and be interested in your partners in every way, and they will not care about the size of your equipment.
