I have a few in my syste who are hesitant about sexuality (either being too young or being men, and thus uncomfortable expressing themselves sexually in a female body) but not everyone in my system is involved with my husband or any of my lovers, nor am I neccessarily involved with theirs. My husband and I are polyamorous and so we encourage each other to seek other relationships and we do the same for the others in our systems (we're also both multiple, which makes things a bit easy on the understanding end as well.)
