So rather wonderfully my (41F) partner (38M) have found a lovely woman that we have been on a couple of dates with and our first threesome seems to be on the cards.

We have talked and talked and thought and thought about all the right things and we are very nervous and of course excited.

We are on the same page that boundaries like no kissing, no penetration with the other woman etc don’t feel good for us because we don’t want her and her pleasure somehow separate/demoted. So boundaries are just around our usual sexual selves (eg no degradation, no pain).

However, I am getting stuck on not being sure how I feel about him ejaculating inside her (with condom) and it’s really annoying me! Why is that particular bit of the act making me feel insecure? I can’t figure it out and I don’t want to say it isn’t allowed as that just feels icky.

We have discussed this with her and she gets it but we weren’t really conclusive about where we would land with it. My partner just wants clear instructions on what I’m happy with 😂

Would love to hear any experiences of what this is like when you actually experience it and if this is something that anyone else has had to work through?

Tl:dr why do I care about my partner cumming inside another woman but everything else feels fine/sexy?
