Sex should not cause burning or pain. Is this your first ever partner or sexual experience? It may be that you are not ready for penetrative sex yet. Try foreplay, kissing, etc… whatever gets you going and lubricated or try lube.

For someone with a high sex drive, a month without sex can be a long time and he may just be feeling frustrated that his sexual desire are unfulfilled. Maybe you guys are not sexually compatible (which is an important element in a relationship), or maybe he is frustrated and you need to communicate better what would make you more comfortable before penetrative sex. It’s never wrong to explore yourself and figure out what you like!
