Intimacy question
I am (M29) and my partner is (F29). We were in a long distance relationship for 1 year then we moved in together in October. Everything was going great. We were having great sex during long distance relationship. After we moved together we had great sex until 2 weeks back. For some reason my penis started to act weird. I started to loose concentration which ruined our sex one time. Then next time it didn't erect. I want to have sex. When we are kissing or cuddling it erects. But when it comes to sex it just sleeps. Any suggestions?
