I would not worry about it. after a while she will feel you with no problom. obviously this other man had a bigger cock but that does mean he can fuck any better. when you are having threesomes the idea is to expericane all people involved. when max and i have threesomes he normally wakes me up around 4 am and screws me silly.. sex is defined in two ways as i see it. there is fucking for pleasure of it and then their is making love. two different things completely. if you are not worried about it tell her so. tell her is does not stop you from wanting her. use her other senses too. fore play can make or break an awesome sexual encounter.
if you plan on having sexual encounters with multipal partners you need to seperate making love from fucking. and you can ot have even a hint of jealousy. enjoy the sex for what it is and take loe making to the next level. spend a lot of time working her body. kissing her all over, petting her, messaging her, take your time. the more you get her excited the better the outcome
best to luck

I wonder too if the guy was bigger, especially in diameter, that your wife stretched open to accommodate that size and when you were inside her just after she was still open to that size. She may want to look in to Kegel muscle exercises which can help with adjusting tightness. You may also want to experiment with a few different size dildos from small to large, for her to get used to wrapping around different sizes. That practice can be fun.

I used to date a gal who had extremely strong vaginal muscles and she was extremely tight. I am just average size certainly not porn star material, we would have to do it for a while before she opened up a bit. When she was so tight I would cum too quickly.

There are similar Kegel muscle exercises for guys too. They help to potentiate orgasm and help you to hold it longer before release. You should do the exercises together, facing each other with nothing on but your intense expressions. I think you'll find both of you so turned on you won't be able to keep off each other.

I agree with Teri, it is about the total package, and I bet you'll find that soon, if not already, you'll fit together fine.

Have fun...A
