do not do anything you are not comfortable with.
some light touching, petting and so forth, might be just fine, .. and that does tend to charge up a sex life.
but if thats all you are comfortable with, set that as a boundary and stick to it.
lots of couples do that, its called soft swing ...
then the couple has sex with each other and its very hot.
just be sure you are totally c omfortable with what you are going to do.
you dont want to have regrets in the morning L
