We both are in our mid 30s. when we get to swingers clubs we tends to find most people are older than us. We are really happy to hookup with older couples they are a lot of fun and zero judgement and just chill. When we say older 45 -55 range.

My husband said everything was amazing but penetration did not feel good as with me. we are new to this and just asking for advise how to go about this. He has never been with older women and really enjoys it with them and doesn't want to disappoint them in anyway and want enjoy himself too.
