Yes and no.
I did once have a relationship where, yes, having boobs was absolutely a plus, at least for a while. In the long term, my awkwardness towards having boobs probably contributed to us breaking up and her ending up with a more traditionally masculine guy with an average chest. When things were going well, yes, it was fun and she and I did a ton of breast play. I don't think most women are into it, but given my experiences and what others have said on this forum, I think finding a woman who appreciates breasts on her man is achievable.
On the other hand, I eventually got breast reduction surgery. Part of me misses my boobs, but I'm glad I did it. Although I could in theory have found someone else who could accept and even like my boobs, dating is already enough of a struggle. Having a more average masculine chest gave me indescribable amounts of confidence. Not having boobs also has allowed me to feel way more masculine. Although I've mostly presented masculine in my life, and I'm pretty sure nobody suspects that I've been anything but masculine, I had some gender confusion for quite a while, and my boobs contributed to that.
