hey. sexual intimacy can be a hard one. i've heard that some people can find a benefit to working on non-sexual kinds of physical intimacy such as massage. it might be easier to stay present for a massage (where sex doesn't follow) than it is to stay present for sex. another thing is that there might be a difference between when you feel in control of the situation and when you don't. some people find they can remain present when they initiate the situation and where they are in control of the pacing etc though they don't remain present if the partner initiates it or if the partner takes control.

maybe there are a couple of things you could try?
