Quick backstory. I left a decades long marriage last year after finally realizing I couldn't suppress my sexuality with an asexual wife anymore and found ENM.

Since then, I've moved out, got my own place, and continued to see one of the girls I was dating when my wife and I tried ENM (which obviously didn't work out). Things with my girlfriend now are amazing. We are absolutely on the same page when it comes to sex, there's nothing we can't or don't talk to each other about, and we swing/have threesomes regularly as well.

What we haven't done is play solo, however, since we got together, we have an agreement that if we're traveling, we're ok to sleep with someone, but it needs to be a one time thing. (I should mention that I traveled this week, did meet someone, we had sex, but I've connected this girl with my girlfriend as well, for reasons I won't get into, but it's all good and we're all happy being connected).

I've learned about myself in the last year (I'm male, if that matters), that I'm not interested in one night stands, or quick hook ups. I genuinely like getting to know someone, and feeling the excitement of them being into me, asking me questions, getting to know me, and a first time having sex. Like, whatever that is called.. that's my kink. It FUELS me. But I don't like the idea of saying "well, that was fun, talk to you never." I really would desire to have more of an ongoing connection with a couple people. I'm not looking for romantic relationships, but there's a few people who have expressed interest in me solo, that I'd be interested in meeting with them also and having an ongoing FWB type thing.

My girlfriend, rightfully so, has labelled this as a big change to our relationship and asked for time to consider the details. We've talked about some of them already, but I wanted to ask a few questions:

1. Am I being totally selfish for wanting to experience that feeling of meeting someone new, getting to know them, and exploring with them for the first time, often?

2. My girlfriend is worried that repeat encounters could lead to feelings. I feel very content with my girlfriend and our life, and can't imagine that I'd open myself up to that, but how do people manage feelings if they do come up?

3. Anything else anyone else has experienced that we should be aware of?
