I don't know extra details about this whole situation, but judging by the LSIs I know, I think you're misunderstanding LSI mindset :
ISTj, LSI (Ti-Se): LF (LSI), as a rule, does not believe in luck but prefers being the "architect of his own happiness." Therefore, he plans everything and steadily moves toward his goals, being distinguished by high capacity for work and absolution from ups and downs of moods. He is responsible, accurate in detail, not afraid of difficulties, both mentally and physically tough.
For all his merits, he has several shortcomings. He is suspicious, poorly versed in the motives and capabilities of other people. Despite the fact that the LF (LSI) can be a pleasant companion, capable of giving compliments and praises to someone whom he likes, he quickly grows tired of this. Then withdraws from the public, submerges into himself. He is not inconvenienced by prolonged solitude. Dispassionate by his nature, he seldom sincerely grows attached to anyone, and for this may be considered an aloof and cold man. He needs an emotive, communicative partner who would be able to affect his feelings, arouse his sociability, fuel and revitalize the relationship with his emotions.
Terms of dualization:
1. ET (EIE) should comply with the main requirements of LF (LSI) regarding planning of affairs and maintenance of order. Do not try to break the habits of LF (LSI) or change his established methods and views on life. If it is difficult to adapt to him, you can try to persuade him otherwise over a period of time.
2. LF (LSI) stubbornly imposes on his partner his methods of work and his own worldview. It is best to accept him as he is, be respectful of his pursuits and interests, giving only the necessary advice along the way. Periodically make compliments and demonstrate your affection.
3. LF (LSI) should give more attention to and trust the advice and requests of his dual, especially when it concerns relations with other people and future prospects. ET (EIE), in turn, may rely on his partner in the official-business and domestic matters, gratefully accepting his care and assistance.
4. With regard to psychological, emotional and sexual aspects of these relations, you need to know that LF (LSI) finds appeal in a partner who is passionate, poetic and willingly talks about his feelings, who is able to "melt the ice" with his strong emotions. At the same ET (EIE) should not rush to close the distance, so that his partner would not consider him too accessible and lose confidence in him. First, the right emotional tone should be created, without resorting too much to candid confessions. Then wait for when reciprocal feelings will ripen, and only then go on offensive.
When it comes to intimacy, ET (EIE) should not rush to show his skill in seduction. LF (LSI) likes a sublime yet modest partner, whom he can teach and show "what is needed" to the extent he deems it acceptable. In this pair, ET (EIE) takes lead in emotional life of the dyad, while sensing remains the sovereignty of LF (LSI). Otherwise there will be disagreement and dissonance.
In sexual behavior of this dyad, ET (EIE) experiences a few problems: he may either be too shy or too direct and frank. His partner needs to show him an optimal style of behavior. Then there will be no need to overcome uncertainty and timidity, nor excessive brazenness and looseness. Without such guidance, ET (EIE) will continue to exasperate and torture himself, and project his dissatisfaction onto his partner. He is in much need of various signs of attention – words, gifts, and gestures – that will confirm the love of his dual.
Relationships in this dyad are built on the principle of "infliction and endurance" ("Kama Sutra"). Therefore, it is sometimes difficult to say who is the "aggressor" and who is the "victim". Both types show obstinacy in relations and often this leads to quarrels. ET (EIE) is able to assert his independence in the psychological play-fighting with his partner, and frequently he wins. However, if he, after all, does not acquiesce and admit to being defeated even a bit, he will have a very difficult time. It is recommended to develop a more harmonious style of communication: ET (EIE) – be more flexible and diplomatic, and LF (LSI) – do not overuse volitional pressure and practice tolerance for weaknesses in another.
Maybe the dude went too far, too soon with striptease and the LSI wants him to cool off a bit.
