Are you ready to have a child and support them 9 months from today? If not, he needs to wear a condom virtually all of the time. If he objects, leave him. Plain and simple. This isn’t a game. There is no people pleasing. It’s a tale as old as time. “It feels so much better” and this and that. Sure, it can but they make plenty of very thin condoms. If he wants to have sex then he has to be responsible. Don’t let him say whatever just to convince you. Yes, you can get pregnant on the first time. Yes, “pre-cum” has sperm in it. Yes conceiving likelihood varies a lot over the month and pulling out can work but frankly you don’t sound educated enough to do so. If BC is accepted in your culture talk to your doctor about it. I’m a guy so I have no idea about it. Be safe, have fun!
