I’m 23 and still a virgin.  I would like for it to be meaningful.  How can I stop myself from being nervous?

You can’t stop yourself from experiencing an emotion you are feeling. Don’t even try.

What you can do is share with your partner(s) the fact that you’re scared.

You can say something like, “I’m feeling really nervous and anxious right now and I would love it if you would reassure me (go slow, kiss me, hug me, tell me everything’s going to be okay, let me take the lead) while we’re doing it.”

If your partner has / partners have the greater experience, they should not have a problem being there for you in this fashion. If they do have a problem, (1) this is not the right time to initiate any sexual activity until everyone’s on board with and clear about what’s going to happen or (2) this is not the right person / people for you to sleep with.

It will be meaningful to you no matter what happens. It probably won’t be great. That comes with experience you’ve yet to develop. Once you know what you and your partner(s) like, your sex / erotic life should improve immensely.

As always, make sure you and your partner(s) are protected against STIs and unwanted pregnancies and give each other active, ongoing feedback, especially when you want to stop or try something different.

All the best.
