Shilajit is popular as a sexual tonic in ayurvedic medicine. However it is not proved by medical test.You follow the suggestion given by the above member.
First of all, I would like to say congratulation on your marriage.
It's not very uncommon to have issues when you first get married because you may not know each other physically yet.
Are you and your wife having any foreplay? If not, I would highly recommend doing so because this will get her ready for intercourse. There is so much more to sex than just intercourse.There's foreplay like kissing, petting, touching each other, oral sex. I would recommend trying all of these things and don't go straight to intercourse. It might be a good idea to please your wife first.Can I ask if you understand how a woman's body works and how to give her an orgasm? If not, I'll send you a private message to try and help you with that.
It's not uncommon for younger men, and newly married men to ejaculate faster than they want to. You can try thinking about other things. You could masturbate in the morning if you know you and your wife are going to have sex that evening.
Another thing I would recommend is getting a water based lubricant. This can be bought at almost every drug store. This can really make insertion much easier.
I'm here if you have more questions.
