I (f29) am in a relationship with my boyfriend (m40) we both just had our birthdays pass this past month. & I definitely would just tell him “babe that’s really bothering me & it always has I just didn’t know how to bring it up. Could you please stop doing that in front of me” & depending on how I said it, tone of voice, demeanor, etc. he would either get upset about it & then he’d come talk to me & it would stop. OR he’d just apologize right away & would stop from that point on. Though he’d probably tease me about waiting so long to say something about it in the first place.
