If he’s young he might not have fully developed his sexual instincts yet. My Pitbull was slow to show interest until he hit about 18 months, even though he was intact. Some dogs are naturally less dominant or sexual. If he’s shy, anxious, or super submissive, he might need extra coaxing to feel confident mounting. My Mastiff was chill and needed encouragement to take the lead. Dogs often need specific cues to spark arousal, like scent, body language, or a familiar setting. If he’s not picking up on those, he might not know it’s “go time

A distracting or unfamiliar setting (loud noises, other pets) can dampen his drive. I always make sure my sessions with my boys are in a quiet, private space. If your bond is still growing, he might not yet see you as a partner in that way. My dogs took weeks of close bonding before they got comfortable with intimacy.
Build a Strong Bond First

Spend quality time strengthening your connection play fetch, cuddle, give belly rubs, or train with treats. My Mastiff started showing interest after weeks of daily bonding, like petting him while he lay on his back. This builds trust, making him more likely to see you as a safe partner for intimacy.Try skin to skin contact, like sitting close in just underwear, to let him get used to your scent and body. Dogs are driven by smell, so this can spark curiosity without pushing him. Get into a position that signals availability, like kneeling on all fours (knees 12-18 inches apart, hips tilted up, as I’ve described before) in a private, quiet space. Do this casually while petting him or playing, so it feels natural. I’d do this with my Pitbull, just chilling in that stance, and he’d eventually sniff and get curious. Expose your scent by skipping underwear or wearing something loose. Dogs are drawn to natural body odors, especially genital areas. Don’t force it just let him investigate if he wants.Move playfully, like wiggling your hips or crawling a bit, to mimic a dog’s playful or submissive behavior. My Pitbull started humping after I did this during playtime it tapped into his instincts.Gently pet his sheath or belly to see if he responds with arousal (red rocket showing). I did this with my mastiff starting with soft touches during cuddles, and it slowly got him interested. Stop if he seems uncomfortable watch for pulling away or disinterest.Let him lick you in sensitive areas (like your thighs or groin) to build familiarity. This was a game-changer with my Pitbull he got curious after licking during play, which led to mounting later. If he humps objects (toys, pillows), encourage it by placing one near you during play. Praise him gently when he does, so he associates humping with positive vibes. Pick a quiet, familiar space, with no distractions, Keep sessions short and fun 5-10 minutes of playful interaction. If he doesn’t mount, no big deal, just try again later. Pressure kills his vibe. Stay calm yourself. Dogs sense anxiety, so deep breathing (like I do during ties) keeps the mood chill. My boys are more likely to engage when I’m relaxed.
Start with non-sexual mounting practice. Let him hop on your back or hips during play (fully clothed), and reward with treats or praise for staying there briefly. My Mastiff took a couple of weeks to get comfy mounting me this way before it turned sexual. Use commands like “up” or “come” in a playful tone to encourage him to approach. Reward any attempt, even if it’s just sniffing or a half-hearted hump. Don’t rush the tie. If he starts mounting, let him explore without pushing for penetration or knotting. My Pitbull took a month to go from humping to full-on tying because I let him set the pace.
That’s key to a healthy bond. If he’s not interested, it could be he’s not ready, not wired for it, or needs more time to trust you in that way. Some dogs never take to mounting, and that’s okay you can still have a deep, loving relationship.
