I am in my mid 30s and have started thinking seriously that I might like to settle down soon. I've just started seeing someone who I seem to have a lot of chemistry with, and the sex is good, but not awesome, more like 7/10. I can't help but compare her to my last ex who I thought at the time wasn't a great fit for me, but who I had absolutely fantastic sex with, like 10/10 every time. I think personality-wise I fit better with who I'm seeing now, but it's not really a huge difference. I've been thinking that if I was with my ex, I would never be seriously tempted to stray at all because the sex is better than basically everything I've ever had elsewhere. But I'm just some guy in his 30s who has never been married...
Any thoughts on this?
