Think about it. A woman's first time is practically always painful and bloody. She risks pregnancy every single time she has it. If she does get pregnant, and can't get an abortion for some reason, then she's going to spend the next nine months becoming increasingly sick and uncomfortable with it only ending in the single most painful experience humanly possible. She also risks permanent damage and infection. All of these medical facts lead any reasonable person to the conclusion that it's in women's best interests if men leave them alone in that way. If men claim to love women so much, then shouldn't we at least put our personal lusts/urges second to their health and safety? Shouldn't we be putting those things above what we want or what they claim to want?
Your understanding of sexuality has given rise to these kinds of questions, or more precisely your complete lack of understanding. A girl's first time for example assume the girl's having intercourse with her hymen still intact which would make her too young to legally have sex in the first place. As girl's go through puberty, the estrogen their bodies are producing causes the hymen membrane to thin, perforate, and eventually dissolve completely. If the hymen's punctured during intercourse, she's still too young to be having sex. Yet an entire myth has formed up around this 'fact of life' to discourage girls from having sex, "the first time's gonna hurt and make you bleed."
Similarly you seemt o be under the mistaken impression a girl's sexual pleasure has something to do with a man's penis. It doesn't. A girl's sexual pleasure is almost entirely located around her clitoris. And stimulating it to orgasm doesn't involve our penises at all. Intercourse feels nice, but there's no mechanism or physical structure in a vagina that would give the woman an orgasm. Yet another myth - "a woman needs a man for sexual satisfaction." Nope.
Taking your premise though and adjusting things a bit, if men loved women so much they should be having sex with other men for recreational pleasure, and only with women for procreation. Worked this way in ancient times and until Christianity came along worked quite well.
