Sex 😛

I'm a virgin but thinking about having sex with my boyfriend who isn't a virgin and he really wants to but I'm not positive what it feels like to know when you're ready. can someone tell me about how they knew they were ready or not ready? I'm also a little worried about how it will feel.. like if I will enjoy it or of it will be painful or something. what does it feel like..? is it similar to being fingered? and when you climax, does it feel the same as when you climax from clitoral stimulation? sorry for all the questions but I need to know 😂. Thanks ladies!!!Â
