Frotting without getting NSFW, is the simulation of penetration without actually penetrating. Usually involving positions like missionary or others, abd the rubbing of parts together. Sometimes hands will come into play as one person holds the "tops" member abd the top will rub the bottoms area. It can be fun, and intense and is quite common surprisingly. Abd if it's someone you're actually interested in dating or seeing after said encounter leaves something to look forward to or build towards. Not everyone is into anal or anal penetration right away and you might need a level of trust and comfort to get there.
