This happened to me once with one of my exs lol. We were hanging out at her house and she came over and sat down on my lap really nice looked me in the eye and we kissed and I instantly got hard just from her kiss and touch. She was sweet and tender. It means that he likes you and is attracted to you lol. Sometimes all it takes is a woman's touch or feel and it turns us on

Some guys can get hard really fast. It depends on all sorts of hormones and how horny he is and all sort of science I don't entirely understand. Some guys can take a few minutes to get there fully, some can be hard as a rock in 30-40 seconds.
