1st ever solo play

[D_****]

So this past weekend had my 1st solo play since starting this new relationship. I felt lost out of place we've played together with other couples since being together we discussed it and we came up with 3 reasons it could be I don't know if they make sense but
1. It was my 1st time and 1st time jitters
2. I need him for comfort in the room
3. I can't play solo anymore
So now to explain how I felt... I was ok with playing solo I've been wanting to for a Lil bit to play with this person and I got the opportunity and I took it so I was 100% on board with it and he was 100% ok with me to play solo. During I kept looking for him wanting him to come in and join but didn't wanna say anything to the other person I couldn't orgasm at all the sex was good he ate good but I just couldn't get anywhere, I've finished everytime we've played as a couple so I know it wasn't because he wasn't there . I ask for permission to cum and was told yes so it wasn't that.. what is your opinion on why I felt so out of place or lost like I did
