33M I'm assuming your stutter just adds to your insecurities. Just want to get this out of the way but having sex is easy. No guy will ever say no to sex because the girl stutters. You're 22 which is very young. You're still learning about yourself. I don't think you should be pressured by family and I'm sorry that you are. You're smart enough to learn from your sisters experiences and good for you. It's totally fine to take your time. Sex really isn't a big deal. Statically the optimal range to meet the partner you will marry is 26-30. You can add raising a family at that range too. And even so some people (like me) are still trying to find their somebody after 30. I think you already know that there more to life than sex and being in a relationship. Set boundaries with those whom don't support you and always strive for your definition of success and happiness
