Like most everything, it will be uncomfortable for a bit. That won’t kill you and ought not disrupt your relationship too much.
Sex with my partner was a battleground when I was drinking. It took time for us to get to the point of loving forgiveness that we needed. And I felt awkward and unsure at 45 years old about how to make love with my wife. But being sober, for me, means believing that everything is gonna be alright. And that’s all or nothing at all for me - so I chose to go with the idea that it will all work out. And it did, and nobody got hurt feelings, and sex is easy and natural today. We know our true rhythm and we dance to that tune.
Your gonna be OK, bro. Don’t think about it too hard.
