Yes, for sure. I like small and medium tits, because its the shape that's sexy not the size. Big ones are liked by girls and newspaper editors, not regular guys.
My G/F and I love to do this, we find it a real turn and have great sex at home later. Last week she sucked me off in an art gallery, late on towards closing time, in a quiet room. I came in her mouth and she swallowed, which was real tidy of her :-)
