I feel like the sooner you mention it the better . I met my fianc online where it had that info in my profile , so he knew before he ever even messaged me . He ' s totally straight . I thought I was totally ace , but as we started to fall for one another I was more and more curious . He ' s the only person I ' ve ever even considered doing physical stuff with , I think because of our connection and love for one another . I ' ve discovered that I enjoy physical stuff , but I also know that we do that stuff significantly less often than the typical heterosexual couple . It ' s all about keeping the dialog open . It seems like your potential SO is really open and respectful of your boundaries . That ' s amazing and hopefully , with good communication , you can learn more about yourself and experiment with how comfortable you are with those kinds of things in a safe and trusting environment .
