I've also been doing it for about three weeks and only got a little bit of swelling two days ago, and I've been noogling 1-2 hrs twice daily. And I think I'm only swelling because it's the week before my period and my breasts usually swell up/ feel heavy anyways lol. So I read this entire thread trying to find the answer to my concern but eh.. I think we should just continue and see.
One thing I 'discovered' though.. maybe try oil instead of your normal lotion/cream. I've tried all my lotion/ creams and finally found one I was quite satisfied with but sometimes the suction would still 'fart'. However two days ago I was too lazy to get my lotion so I just used a few drops of jojoba oil and WOW I got no farting, and SWELLING! and it was so much more comfortable and my skin looked good afterwards too lol. So maybe try that.
