I totally understand the ick factor. Sometimes it was triggered by guys acting attracted to me. If someone makes you feel icky, there's probably no hope for a long term relationship.

A couple years ago, I did worry I had commitment phobia. I got pursued by an aggressive older man and because he was my parents' age, I had a hard time cutting him off because it felt like disrespecting seniors.

After that I felt panicky whenever an older man wanted to be friends and I thought somthing was wrong with me. But the next 2 older men ended up wanting more than friendship and behaved inappropriately so now I learn to trust my gut and cut them off as soon as it feels wrong.

Likewise, I think the ick you feel may be your intuition telling you something is not right. When I make an effort to avoid being grossed out by a guy or try to convince myself they are ok, it usually turns out badly. I think you should trust your feelings. Maybe you are more reserved or have higher standards in your preferences. There's nothing wrong with that.

I think when you meet the right person, they won't feel icky to you. It's natural to prefer partners whose attractiveness is similar to yours so you may prefer to date other models. That's ok so long as you are mentally compatible as well.

Sometimes the ickiness will go away if a person is cool and becomes friends with you. But I find that it doesn't work if the icky person keeps pursuing you in a romantic way. Just do what feels comfortable and don't feel pressure to date anyone unless you really want to.
