Do You Consider This Chastity?

I am a married man in his mid-fifties. Our sex life used to be very active, but medical issues have caused my wife’s desire to drop over the past two years. We still have intercourse a few times each month… sometimes penetrative, and I also give her oral pleasure. So far she hasn’t shown much interest in chastity devices. I’ve been exploring it on my own… What I actually do is tease myself for days or even weeks without ejaculating. When the pressure feels too high, I milk out some fluid to get relief. However, I try hard—by all means—to avoid any kind of orgasm while pleasuring myself. During sex with her, I reach an orgasm maybe once or twice a month. So yes, I watch porn, stroke my cock, and do not wear any chastity device. Would you consider this “chastity”?
