It can feel good, but for someone who was teased about having boobs as a teenager, it can be distressing. Other guys in high school used to squeeze my boobs as a joke, and for the longest time after that I would never let a woman touch them. I am just now getting comfortable with it.
If it feels good to have your breasts/nipples touched or played with why would you want to avoid that. Be honest with your partner and you might be surprised.
My partner actually likes to play with them. If you have sensitive nipples let them out to feel good.
