Dick too big...

I’m a virgin and straight up scared to have sex with my boyfriend lol...

He wears Trojan magnum and I’m five feet and idk i just need advice. I’m okay with having sex and I want to have it with him (he hasn’t pressured me at all), but I guess I’m just really nervous about the pain and being inexperienced. Especially since I’m pretty darn small and he’s big lol. He’s also really experienced so I guess it makes me even more nervous about the fact that I have absolutely no experience. Ahhhhh
