TMI help nipple stimulation

Okay so with my son I hated any nipple touching in regards to pleasure. So breastfeeding my baby wasn’t any dramas. Anyway a few months back I recently been really like really enjoying nipple stimulation when pleasuring myself (don’t let partner know about this) anyway I’m pregnant with #2 and I still can’t stop I’m so worried I won’t be able to breastfeed without thinking of the pleasure side. Anyone else thought the same and was horribly wrong??
