You said; "We are sexually active" but he doesn't kiss you?
Have you ever attempted to initiate a kiss? If so did he turn his head or push you away? To be quite honest with you it's hard for me to imagine a couple dating who go from conversation to sex without (ever) having kissed one another!
If you're having sex that isn't exactly taking things "slow" just because there is no kissing. A kiss was considered "first base".
I could understand it if one person was a prostitute and the other was a paying client. When I was growing up the we use to say:
"The kiss is the persuasion to lower invasion."
In other words kissing was part of the foreplay! As a man the only way I could imagine never kissing someone I was dating would be either she has bad breath or I suspect that I have it. Either way I would not be involved with anyone who I felt was not kiss worthy!
I remember watching the movie "Pretty Woman" with Julia Roberts many years ago. She plays a prostitute and refuses to kiss Richard Gere (her trick) early on because kissing is "too personal" and intimate. Everything else was available for him to do whatever.
No one I know of envisions having a relationship with someone who refuses to kiss them. Next thing you know sex is (always in the dark) with your back to him! Essentially any woman in that scenario is being dehumanized to the level of sex toy. One man's opinion
