The Yahweh/Jesus combo god would be the worst people to give sexual advice to anyone. I rest my argument on two lines of evidence:
A. The perverted views of Yahweh/Jesus, as expressed in the Bible.
A1. To punish David for his sins, the Yahweh/Jesus Combo God, promised to allow some other man to rape David's wives. See 2 Samuel 12: 11
11 “This is what the Lord says: ‘Out of your own household I am going to bring calamity on you. Before your very eyes I will take your wives and give them to one who is close to you, and he will sleep with your wives in broad daylight.12 You did it in secret, but I will do this thing in broad daylight before all Israel.’” (NIV)
These poor women, had done nothing wrong, but Y/J was going to have them publically humiliated, by being raped in public. Not only a perverted punishment, but an unjust punishment.
A2. If you turn your Bible's to Judges Ch. 19, you will read one of the most sordid stories it is possible to imagine. (I'm using the NIV). The story (probably, a re-write using the Sodom and Gomorrah story as a model) includes adultery, an attempt at homosexual rape (vs 22), and a actual gang-rape leading to a woman's death from her injuries.
But that's not the key point. There has to be retribution, so "all" Israel unite to punish the whole tribe of Benjamin (from which tribe came the miscreants) and slaughtered thousands of the Benjaminites, AND the "innocent women" (and, probably the children also. Realising that the tribe of Benjamin would likely disappear, the Israelites (God's chosen people - ever wonder why after reading this rubbish?). So these prize idiots (i.e the Israelites) decide they'll kill all the males at Jabesh Gilead (because they refused to take part in the above stupidity) and give the young virgins (400) to the surviving Benjaminites (is that where ISIS got the idea?). But therew's not enough women to go around. So some really bright spark said, OK! there's a festival coming. When all the young women are dancing, you (the men of Benjamin) hide in the bushes, jump out and grab one carry them off. (a licence to rape). (Ch 21: 20-23)
So that's a second reason why Y/J is not a good source of advice.
Then there is this:
B. The perverted views of Yahweh/Jesus as evident in creation.
B1. Cross-dressing is forbidden in the Bible, but just look at what the Yahweh/Jesus combo god design team made in creation;
This poor little insect was created by the Y/J designers with the female having a penis (as illustrated) and the male having a vagina. Yahweh/ Jesus is perverted. http://www.livescience.com/44906-female-insect-with-penis-found.html
If you don't believe this argument, take a peep at some other images of the Y/J design teams perverted designs. (Warning, not for faint hearted ladies or men)

B2. It is possible to write a book on weird sex in Y/J's creation. To keep this short, just check out this overview of twelve of the Y/J's weirdest sexual experiments at:

Which include this little horror. As described in the above link:
This is the pirate bug's penis: "Its spiny penis is razor-sharp, and instead of inseminating females by traditional means, the bug uses its sex organ to violently stab through her exoskeleton in order to ejaculate. This leaves "gaping, seeping wounds" in female pirate bugs, who often die shortly after giving birth."
