If something upsets you in a relationship, you should feel absolutely comfortable in expressing your displeasure, and he should respect you enough to stop, particularly if the source of displeasure is sexual in nature. You are not there to be fondled at his whim and fancy, and frankly, I find his behavior both unusual and highly disrespectful.
Speak to him about this, and explain that it makes you uncomfortable, and that you request he stop. Find out why he does this...lots of people are in love and don't operate under the same groping that you do, so I find his current reasoning to be flimsy at best. If he has the respect for you that a spouse should have, this should cease.
Please know you're in my thoughts and prayers, and I hope things work out for the best.
Hugs,
Harley
