while it is online, t and I have a sexual relationship that my wife is aware of. typically it is camming to orgasm. my wife was ok with me buying lingerie for t as well as sending her a sex toy.
im not sure either of us could enjoy boundaries in person, but it is worth exploring.
if nothing else I do need to find out where the boundaries are. I would even be interested in sleeping (literally) with t with clothes on, but I suspect its a real life intimacy boundary and not a sexual one.
