My bf snores and my late husband snored. I wear a thick soft eye mask (from the Brookstone store-- I believe Honey has a grudge against them ) and foam rubber earplugs from Walgreen's. I even wear these to sleep or nap alone. Your body needs pitch blackness to make melatonin so you can sleep. In these days of digital clock readouts, and tons of ambient light, darkness is hard to achieve. This mask does the trick. Ditto the earplugs for total silence. VERY relaxing.
Also, don't push the no jammies issue. Jammies/no jammies are not the crux of the problem. My bf and I sleep stark staring nude together every night, fully spooned, and haven't had sex in months.
