Men and women for natural parenthood meeting

There's always plan B. Somebody said. I am a single male and never been w a female unprotected. Id like to meet adults who also enjoy and ok with a baby. Babies are a blessing. Sex is naturally about reproduction and being 48. Ideally id like my partner and myself to be each other's first. Dont judge but id like to be her first as well but I think if she desires a large family its a fit. It isn't so much abt impregnation per se but abt being normal people with biological needs. Id like to know if any people from san antonio tx think abt this topic and where it should or shouldn't go.
