To wonder if I should tell him?

[ThisIsAnAwkwardSituation]

This is embarrassing but here it goes.

I'm 25 years old and have never had sex. This sounds childish and immature but never really been interested and didn't feel ready.

However I have been seeing someone for about a month now and things are getting serious. I would like to do it now, but I'm just confused about whether I'm supposed to tell him about my lack of experience? And more to the point, how do I tell him? Does it really matter if I don't tell him?

He is four years older than me and from what I've gathered very experienced so I think I'm going to feel childish.

I was thinking about not telling him and just going for it. Good idea or not?

:( it will get better but when your ready. Hopefully you wont experience the bleeding again!

Sorry but the guy sounds like a total childish jackass.
Hope you are ok OP

Yes its fairly underwhelming tbh. Then you get to find what you like and it will become pleasurable for both of you.

Another one here advising you to experiment yourself when the soreness has gone.
Now that you are not going to cause any damage to your virgin state, you can some relaxed sessions with a suitable hand-held 'friend' and really find out what works best for you. Then you can guide your partner - whoever that may be - next time.
When you get it right, the sensation is absolutely fantastic.
Enjoy!
