I tried casual sex in my 20s but couldn't handle the emotional disconnect aspect that is par for the course with the other person. Sex is good for the mind, body, and soul. But so is masturbation. So if you're hesitant to have casual sex, then just masturbate a lot. Masturbation helps you connect with yourself, it builds your sexual stamina, relieves headaches and body tension, lowers blood pressure, can act as a natural sleep aid, combats depression, boosts your immune system...the list of benefits is long.
