At 6 weeks post-op, you're at the very beginning of your recovery. This recovery takes 6 months or the majority of healing and a full year for the rest. I even had improvements into the second year. Your upper GI tract has been completely revised, and it takes time to heal and adjust.
The problem with laproscopic surgery is that your outsides don't show the mayhem that went on inside your body. Your incisions are healed and on the outside you look recovered. On the inside, your organs have been moved around to get to the surgical site, and your stomach has been stretched, wrapped, and stitched, and is complaining loudly about now.
As far as the sex discomfort goes, keep in mind that your insides have been through a lot, and it will take time to get comfortable again. Look for positions that put the least amount of stress on your internal organs. This isn't a forever thing. You'll find that as healing progresses, things will improve.
It's a bummer that you needed this surgery at such a young age, but it's not all that uncommon as I'm finding on this forum. Still, with time you'll be glad you did it. Most of us find it hard to deal with the early recovery months.
You do have to be very careful with taking small bites and chewing carefully. I went by the rule that I wouldn't swallow anything that couldn't be chewed completely. I'm 3 and a half years post op now, and I'm still careful to eat more slowly and chew my food completely. The wrap creates a barrier that works both ways...less acid refluxing, and a more challenging entrance for food to get into your stomach.
You're having continued swelling at your stage of recovery, which makes it more difficult to swallow than it will be after your recovery is complete. Although I'm still careful, I can now swallow things that aren't completely chewed. Some things don't chew to a liquid...clams and carrot sticks for instance. I can eat everything now, but as I said, I eat more slowly and chew more completely than I did when my LES was loose.
Still, I'm very happy with the results. My lungs, which were badly affected by my reflux, have healed and are doing just fine. My voice is back and I can sing again--that was a long haul, and it's just now gotten to that point. I'm just so happy I had the surgery, and I'll bet you will be, too, once you've completed your recovery.
Good luck, and hang in there!
