Re: High libido, not enough sex
Sounds like you are a little obsessed to say the least......
I can tell you that if the sex is insufficient now prior to marriage then just wait till your married, it will drop by half. Have a kid or two, half again.
You need to start out at pretty compatible level because it will drop off after marriage and kids.
So I would suggest two things
Cancel Engagment and look for a more compatible partner.
Get some therapy as you do seem to be someone overly obsessed and this is coming from a pretty high libido guy.
